Quest audit: how quests fail or get stuck (2026-10-30)

Request (2026-10-26, started 2026-10-30): "iterate through all quests in the game, and check their conditions for potential failing or stuck up points given the current implementation and our attempted reset". Done one quest at a time from the compiled scripts with tools/questscript.mjs (full dump: <dir> <id>; compact: <dir> --facts <id>).

Scripts: Ancaria per hero class bin\TYPE_NPC_<class>\ (the game writes the one in use to bin\sgf.bin; this audit reads TYPE_NPC_GLADIATOR, the class variants differ in a few class quests), Underworld bin\Addon\NetScriptCamp\. Ancaria: 603 quests in the table (87 + 13 side quests, ~37 main quests, 352 generic DQ_ quests from 16 templates, multiplayer / unnamed sets); Underworld: 190.

What our mods do (the "reset")

• M1 failure restart (questfail.cpp, Quest_End hook): after LoseQuest ran the quest's failure script (QIS_OnLose<id>), the flags go back to available (1), the book entry stays failed with its compass on the giver. Quest variables and NPC states are left as they are.
• M2 giver death (questgiver.cpp): a label of a running quest run for its dead giver (the giver: the NPC spawned with a dialog that has the accept button) is skipped, unless the giver is hostile to the hero (2026-10-30); the quest restarts (M1 plus the variables only this quest writes: 0, the one named after the quest: 1) and the giver's spawn instruction runs again once the body is gone.
• M3 load repair (questgiver.cpp): a running quest whose giver is not alive after loading gets M2, unless the quest morphs its giver.
• M4 followers (followers.cpp): escorts back on the hero's follower list after loading; followers more than 40 cells away are teleported to the hero.

General findings

• G1 M1 keeps the quest variables. Givers' dialogs choose their branch by bits of the quest variable (IF 49(bit, "<id>")); bits set while the quest ran stay set after a failure, so the giver shows a "still running" branch without the accept button and the quest can never be taken again. Example 702: the girl's death runs lose702; variable 702 keeps bit 1, the giver answers "Qoffen01" with ok702. Fix: M1 resets the quest's own variables like M2.
• G2 generic quests (2600..3599) are the game's random quest pool; Quest_End already copies them under a new id. M1 should leave them (and their runtime copies) to the game.
• G3 one-time world progress. Many targets are spawned once by the start script or Region<N>Init, not by the quest. When M2/M3 reset the quest's variables after such a target died, the progress is lost and the target never comes back: stuck. Either keep the variables on M2/M3 or respawn the quest's one-time NPCs (see G6).
• G4 duplicates on re-accept. QIS_OnEnter creates the quest's NPCs and objects again; after a failure the old ones may still be alive.
• G5 givers deleted by the script (DelNPC on the giver): M3 restarts a quest whose giver is gone on purpose.
• G6 restart without the NPCs. The restart is pointless when the NPCs the quest needs are one-time spawns and dead or deleted. Idea: respawn them from their spawn instructions like the giver.
• G7 quests without a giver (trigger areas): M1 "restarts" them and erases the failed book entry.
• G8 givers turned hostile by SetNPCState ... 08 12 instead of Morph are not in g_giverTurns; M3 restarts those quests wrongly, M1 points the book at an enemy.
• G9 shared variables. M2 doesn't reset quest variables another quest's label also writes, so the respawned giver shows a running branch.
• G10 giver killed after the quest ended (by its own script): M2 doesn't act, the giver stays dead.
• G11 failure continues a chain. Some failures are part of a quest chain (LoseQuest together with SetUpQuest of the next quest, giver's dialog moved on); M1 must not restart those.
• G12 state in dialogs (Underworld). Underworld quests keep their state in the NPCs' dialogs; a failure sets a "done/lost" dialog (or none), and M1 doesn't put the accept dialog back (7614, 10260).
• G13 named ids. Spawns with named ids (res:AUFTRAGGEBER_10254, res:Sam1_Knappe) or the id after the type argument aren't read by InstructionScriptId; those givers aren't in g_givers.
• V1/V2 vanilla bugs: 1101's time-out never ends the quest; Res:17163 is used by both 602 and 1202, and 602 deletes 1202's patient.

Per quest

Columns: how it can fail (vanilla), what happens with our mods, verdict (ok / G / finding).

Quest	Fails by	With our mods	Verdict
151 Tierischer Wilddieb	never (no LoseQuest); wolf Res:17081 (start script, death stirb151: bit 2, triggers the quest)	M2/M3 on giver death: variable 151 reset to 1; if the wolf is already dead, bit 2 is lost and the wolf never respawns: stuck	G3
152 Botendienst	time limit (SetTimer 4320 -> zeit152: bit 4, LoseQuest)	M1: bits 1 + 4 stay, the giver answers "Qfail" / "Qpostfail" without the accept button: stuck. With G1 reset: offered again; re-accept spawns the parcel (Res:6027) and later the recipient Res:17077 again (the old recipient stays, dialog off)	G1, G4
154 verschwundener Schmied	never	the script deletes the giver Res:17626 (talkedbride154, take154): after the next load M3 restarts the running quest and spawns the giver again	G5
201 Vermisste Tochter nach Ausritt	daughter Res:18006 dies (Tochtertot201: bit 8, LoseQuest); she is spawned once (Region2Init)	M1: bit 8 stays, giver answers okt201 then ok201: stuck. With G1: offered again, but the daughter stays dead: cannot be finished	G1, G6
202 Eskorte für Händler	merchant Res:18012 (the giver) and bodyguard Res:18013 both dead, or the bodyguard alone at the bridge	the merchant's death is M2 (restart, respawn; his dialog has no bit tests); the bodyguard is not needed	ok
203 Schatzkarte	never	giver death -> M2; re-accept creates map + chest again (old chest stays)	ok (G4)
204 Die Bücher der Gelehrigkeit	never	giver death -> M2; the boss and the book come from QIS_OnEnter204, so a restart can be redone	ok
301 Orks auf Bauernhof	time limit (SetTimer 1440 -> lose301); farmer Res:17033 and daughter Res:17032 both dead	no giver (trigger area, deleted on start); QIS_OnLose301 deletes both NPCs. M1 makes it available but nothing can start it again, and with no known giver its failed book entry is erased	G7
302 Von Räubern und Rindern	six cattle dead (302a = 6, LoseQuest); the giver Res:17029 (escorted) dies (tot1_302)	giver death -> M2 (but 302a is also set by startcode, so it is not "only this quest's" and keeps its count). Cattle failure -> M1: the dialog's 48(6,"302a") branch sets bit 3 -> "ok" forever: stuck, also with G1 unless G1 counts start-script initialisation as the quest's own. Re-accept spawns the six cattle again	G1 (start-script variables), G4
303 Bodycount Orks	never; ogre Res:17031 is a one-time spawn (Region3Init, death tot303: bit 2)	as 151: giver death resets bit 2, a dead ogre never returns: stuck	G3
401 Jagd auf wildernde Wölfe	never; wolves one-time (Region4Init, death stirb401: bit 2)	as 151	G3
402 Kräuter für Kräuterhexe	never	herbs from a permanent MouseEvent (Region4Init), can be picked again after M2	ok

501 Geister auf Landsitz	never by LoseQuest; choice change501 / nochange501	postchange501 turns giver Res:17071 and Res:17070 hostile with SetNPCState ... 08 12 (not Morph): M2 sees the hostility at death, but M3 after a load would restart the quest (only Morph is known as "turns")	G8
502 Verstecktes Waffenlager	never	enemies and boss from QIS_OnEnter502 (variant by Globalchange1): redoable after M2	ok

801 Holzfällerstreit mit den Elfen	the giver Res:17144 dies (tod801 -> lose801)	giver death -> M2 (restart, respawn) instead of the failure	ok
802 Königliche Jäger Verschollen	never	hunters, herbs and amulet are one-time (Region8Init); M2 resets 802 (progress bits): stuck when they are used up	G3
803 Kopfgeldjagd	never	targets one-time (Region8Init). On giver death M2 does not reset 803 (quest 801's elf dialog also sets a bit in it), so the respawned giver shows the running branch without accept and the flags say "available": stuck	G3, G9
901 Soldaten verschleppen Frauen	time limit (zeit901, also kills quest 902's women); the women Res:17051..17054 die (lose901: bit 5), then the giver's answer runs lose901	M1: bit 6 stays, giver "ok901": stuck.

1102 Kompromittierende Situatuion	time limit (Zeitum1102: bit 3, LoseQuest)	M1: bit 1 stays, giver "Ok1102": stuck; with G1 redoable (the lady and the letter come from QIS_OnEnter1102). After the time limit the lady's bit 3 answer kills the giver (SetHP 0); the quest is no longer running then, so M2 does not respawn him	G1, G10

With G1: the Animagus is one-time (Region111Init). postchange1112 turns the giver hostile by SetNPCState (M3 after a load: G8)	G1, G6, G8
1113 Elfischer Kunstraub	never	thief Res:17129 and the goal object Res:6052 one-time (Region111Init)	G3

2101 Hands of my Dragon	never	chain with 2102/2103 (and 2303's egg) on dragon Res:17245 (one-time); prince Res:17246 and his guards from QIS_OnEnter2101. Shared variables riesendiamant/drachenei are written by several of these quests (G9 if one is restarted)	ok

2402 Verlaufene Sielder finden	the settler dies after joining (losequest2402)	the failure continues the chain (SetUpQuest 2403, giver's dialog set to 2403); M1 restarting 2402 is wrong (G11)	G11
2403 Verschleppte Sielder befreien	all settlers die (losequest2403)	like 2402: the failure continues the chain with 2404 (G11)	G11

2502 Eierdieb	the time-out, reported to the giver (losequest2502)	the failure counts towards the region's finale (bit 2 + finalestart) like a success (G11); after M1 bits 4/5 stay (G1)	G11
2503 Drachentöter vertreiben	never	dragon slayers one-time (region init)	G3
2504 Rette Jungfrau	the maiden (= giver) dies (lose2504)	M2 catches her death first: restart and respawn instead of failure + finale bit; redoable	M2 changes vanilla
9003 Versteckter Händler	rg3_goodie1_lose (merchant's death)	progress lives in the shared variable goodies (8 quests), M1/M2 can't reset it (G1 + G9): after M1 bit 1 stays and the dialog offers the reward branch (ExitQuest) without the quest running	G1 + G9
9004 Vermisstes Kind	rg1_goodie_lose (child's death)	goodies bit 4 stays, the giver only answers "ok" (G1 + G9); child Res:17513 one-time (G6)	G1 + G6 + G9
9005 Der Waldläufer	never		ok
9006 Der unbekannte Krieger	never	progress in shared goodies	ok
9007 Jacquaire's Waffen	never	guards from QIS_OnEnter9007	ok
9008 Furchtbares Verbrechen	escorted giver Res:17539 dies (losequest9008)	M2 catches the death (restart, respawn); QIS_OnEnter9008 sets the trigger area again	M2 changes vanilla
9009 Whiskeylieferung	never		ok
9010 Vergrabene Sklaven	escorted giver Res:17575 dies (lose9010)	M2 restarts; but 9010 is a counter (0 = offer, needs key Res:17580 in the inventory), M2's reset to 1 shows the "follow" branch, and QIS_OnEnter9010 deleted the key, so it can't be accepted again (G6)	G6
9011 Jacquaires Vergangenheit	never	boss and target from QIS_OnEnter9011	ok
main quests 1-81, 670	never	started by trigger areas (SelfTriggerQuest<N>), no giver, so M1-M3 don't touch them; 31's giver is only set by SetNPCState (not in g_givers)	ok
65 Trockenlegung durch Zwergenstaudamm (main)	never	giver Res:18306 (Torfstecher, start script) is in g_givers. Vanilla his death leaves 65 unfinishable (61 is activated by Exit65); M2 brings him back, but resets 65 incl. bit 5 (pump switched by SwitchPump65); if the pump can't be used twice the quest is stuck (G3). Re-accept creates the rune Res:17569 again (G4)	G3 + G4
210 Verschleppte Novizinnen in Räuberöhle	never	boss Res:17083 one-time (start script)	G3
9000 Das Untotenlager	the shaman's drop is picked up while the quest runs	refusing makes the giver Res:17500 attackable by SetNPCState 08 14 (not Morph, G8); killing him drops the item whose label opens the Khorad Nur gate (ablehnensieg_goodie_wueste). If M2 sees him as not hostile it skips drop_goodie_wueste: no item, the gate (main quest 55's way) never opens. Check IsHostileTo for 08 14	G8, critical
5003 Opferritual	the hero refuses at the end (nein5003)	a story choice: the shaman Res:17699 and his tribe turn hostile (SetNPCState 08 12) and the quest fails. M1 restarts it with bit 6 kept, so the (now hostile) shaman would offer the choice again (G11 + G8)	G8 + G11
5005 Pony Express	a time limit runs out (losepe)	losepe deletes the giver Res:17753 (spawned once by main quest label NachOrkland55) and all stations; after M1 the book points at nobody and the quest can't be taken again (G5/G6); 5005c stays (G1)	G1 + G5
6001 Die Invasion der Eiselfen	all elves of the camp die (od_welfen6001)	after M1 bits stay (G1); the elves (incl. giver Res:17706) are one-time, dead (G6); re-accept creates the invaders again (G4). Accept label starts with SetNPCState, so the giver isn't in g_givers (no M2/M3)	G1 + G4 + G6
6002 Das Orklager	never		ok
6003 Elfenbeschützer	the escorted elf Res:17750 dies (lose6003)	after M1 bit 3 stays (G1); the elf is one-time (G6); her dialog is set by SetNPCState, so she is probably not in g_givers (no M2)	G1 + G6
2600-3599 generic quests (16 templates × 22 regions)	DQ_RG<n>_..._LOSE_<id> (and _ABORT_ for escorts)	no giver (runtime-assigned NPC), so no M2/M3; M1 restarts them although Quest_End already copies them (G2)	G2

Underworld quests keep their state in the NPCs' dialogs (SetNPCState ... dialog"dlg_<npc>_<id>_<step>"), rarely in variables, and most givers are spawned by QIS_OnSetUp<id> (run from the start script) without a dialog.

Quest	Fails when	Finding	Class
7612 Eskorte	escorted Nanoduk Res:19547 dies (od_nanoduk)	he is the giver and one-time (QIS_OnSetUp7612); after M1 nobody offers the quest (G6)	G6
7614 Vermisstes Kind (Underworld)	the child Res:19549 dies (od_erdriac)	the giver's dialog is set to the "child is dead" step _d (only "ok"); M1 doesn't restore the accept dialog _a, so it can't be taken again (G12). The child comes from QIS_OnEnter7614	G12
7617 Eskorte in den Süden	escorted giver Res:19586 dies (od_7617)	he is spawned with his accept dialog, so M2 catches his death: restart and respawn	M2 changes vanilla
7619 Tod den Toten	the giver Res:19545 dies (od_threepwood_7619)	his accept dialog is only set by SetNPCState in QIS_OnSetUp7619 (not in g_givers); after M1 he is dead (G6)	G6
9518 Unter der Herrschaft von Dämonen	the mother Res:19530 dies while following (od_lose9518)	after M1 bits 1/2/4 stay, the giver only answers "ok" (G1); re-accept creates mother and demons again (G4)	G1 + G4
9520 Cookies Quest	the hero gives the cookies to Von Endlich, then the girl ends it (btn_FinishLose9520, gold for experience)	a story choice (G11); after M1 bit 4 stays, so the girl offers btn_FinishLose9520 again and again (repeatable gold-for-experience trade)	G11
10254 Der Hilferuf	the giver dies (od_Auftraggeber_10254)	the giver is spawned once when the letter is picked up (ot_Brief_10254); after M1 he's dead and the letter gone (G6). The 10250-10261 givers have named ids (res:AUFTRAGGEBER_10254, after the type argument), which InstructionScriptId doesn't read: none of them is in g_givers (G13)	G6 + G13
10255 Panik vor Spinnen	never (its "lose" is a label name; the giver offers a restart himself)		ok
10260 Das Rätsel in der Wüßte	the wrong chest is opened (fillchest_chestQJ_0x)	the giver's dialog is removed (0a#0); after M1 nobody offers it (G12)	G12
other Underworld quests (main 11-56, 7600-7630, 9511-9522, 9900, 11101-11110, 15001-15084)	never	main quests have no giver (untouched). Side quests: givers spawned with their accept dialog in QIS_OnSetUp<id> are in g_givers (7600, 7601, 7605, 7609, 7614, 7617, 7618, 7620, 7622-7624, 7626, 7630, 9511, 9513, 9515, 9518, 9520, 9521); a chain's later quests on the same giver (dialog by SetNPCState) are not. Their targets also come from QIS_OnSetUp (one-time), so M2 after a target died loses progress only where variables hold it (G3, rare here); named ids (res:Sam1_Knappe, res:AUFTRAGGEBER_…) are skipped (G13)	ok / G3

Summary and proposed fixes

Counted over the side quests (Ancaria 151-2504, 9003-9011, 210, 65, the 5003-6003 set and the Underworld quests that can fail): about a third are fine, the rest fall into the classes above. In order of impact:

1. G8 critical, 9000 (Khorad Nur gate): verify by a log whether a creature set by SetNPCState ... 08 14 is hostile to the hero (IsHostileTo). If not, M2 skips the shaman's death label and the gate never opens. Fix either way: treat a giver as "turned" when any of its quest's labels set 08 12/08 14 on it (extends ScanGiverTurns beyond Morph); that also fixes M3 for 1112, 1301, 1701, 2003, 2201, 2202, 501, 5003.
2. G1 reset on failure: M1 resets the quest's own variables like M2 (including the ones only start/region scripts initialise, with their initial values, e.g. 302a, 2001a = 1). Fixes most "giver only says ok" cases (152, 702, 703, 1002, 1003, 1302, 1303, 1401, 1404, 1602, 1803, 1903, 9518, ...).
3. G11 failures that are part of a story or chain (2402, 2403, 2502, 5003, 9520): M1 must not restart a quest whose failure label also calls SetUpQuest/finalestart, or sets the giver hostile.
4. G2 generic quests: M1 leaves 2600-3599 (and their runtime copies) to the game.
5. G6 restart without NPCs / G3 lost progress: the bigger design question. Options: (a) on restart, respawn the quest's one-time NPCs from their spawn instructions in start/region scripts (like the giver), (b) keep the variables on M2/M3 (no progress loss, but the giver may answer with a running branch), (c) don't restart quests whose needed NPCs are gone and leave them failed. Recommendation: (a) for NPCs the quest's dialogs or death labels name, else (c).
6. G4 duplicates: before re-running QIS_OnEnter, delete the quest's still-alive named NPCs/objects it is about to create.
7. G5/G7 (154, 301, 1502, 5005): M3 skips quests whose labels DelNPC their giver; M1 skips quests without a giver.
8. G9/G12/G13 (803, 9003/9004 goodies, 7614, 10260, named ids): lower priority; G12 needs the accept dialog put back (it is in the giver's spawn instruction or QIS_OnSetUp).

Fixes (2026-10-30)

Request: "all, but leave 1, as i cant play for now" (2-8 above; G8 waits for a measurement in the game). Not yet tested in the game.

• mods/questscript.cpp (new) reads the script code once and keeps, per quest: the giver (spawned with the accept dialog, else given it by an NPC state instruction: the Underworld's QIS_OnSetUp<id>), its variables (set only by its labels, plus the one named after it: G9), what QIS_OnEnter<id> creates, the NPCs it needs (its labels set their state, don't create them), whether it morphs or deletes its giver, and the failure labels that end its story (LoseQuest with SetUpQuest/ActivateQuest, experience or gold, a call into another quest's label, or an NPC offering the quest turned hostile or set to 0 hit points: 1701 ende1701, 1703, 2402, 2403, 2502, 2504, 5003, 9520). It also keeps the labels running (for Quest_End) and spawns NPCs once their bodies are gone.
• questfail.cpp: at Quest_Trigger (first time) the quest's variables are kept ("questVariables" with the hero). A failed quest stays failed when it is a generic quest or a copy (G2), has no giver (G7), its failure ends the story (G11) or its giver / an NPC it needs is gone without a spawn instruction (G5/G6). Else the restart also: resets its variables to the kept values (G1; without them: 1 for the one named after the quest, 0 else), deletes what QIS_OnEnter created (G4), spawns dead needed NPCs and the giver again (G6, from region start labels, another quest's label or QIS_OnSetUp), and gives a living giver the accept dialog again (G12). After a load, failed quests restarted earlier get their variables reset (repairs saves stuck by G1).
• questgiver.cpp uses the same scan; the load repair skips quests that delete their giver (G5); the giver comes back through questfail::Restart.
• Not done: G8 (fix 1), G3 for progress held in one-time objects (2203's barrels), G10, G13 (named ids such as res:AUFTRAGGEBER_10254: the game's name table is unknown, those givers can't be checked or respawned).
