Guild Wars 2

Since ascalonian catacombs are a bugridden mess, I thought I’d list the dungeon breaking bugs that I know of and how to prevent them. All of these bugs will (if encountered) force you to completely restart the dungeon. There is no way to fix the path after encountering the bug.

I have encountered all of these bugs myself and confirmed the triggers in some duo-runs.

P1 The endboss does not spawn
This bug is triggered if, after collecting the sceptre-pieces, someone crosses the grastling tunnels before the event spawns that tells you to do so. In this case the event “Explore the graveling tunnels” can no longer be completed. The boss spawns only after it is completed.

Fix: Only enter the tunnels after the event spawned.

P2 Detha does not talk to the Ghost and does not build the traps
This bug is triggered if, after killing the grastling breeder in the room with the spike-traps, everyone ports to Kholer’s waypoint before Detha says her sentence.

If all players are too far away from an NPC, the NPC will teleport after them. This mechanic sometimes triggers even though the NPC still has something to do (in this case say a sentence). Forcefully removing an NPC from a location where he/she needs to perform a task will make them unable to complete that task (even if you revisit that place with them). Since the dungeons are linear, the NPC can only start his/her next task (in this case talking to the ghost) after the current task has been completed.

Fix: One person has to stay with Detha in the spike-trap room until she says her sentence.

P3 The path to the endboss does not open
This bug is triggered if, after destroying the 4 big grastling-burrows in the great hall, all players port to the new waypoint and at least one NPC was still at the beginning of the great hall. In this case the NPC is ported before he can start his dialogue, which prevents the dungeon from progressing (s. P2 Detha).

Fix: One person has to stay in the hall (you are free to loot the chest in the meantime) until both NPCs have said something.

P2 Detha does not build the traps after talking to the Ghost
This bug has been fixed. There is no more need to make Detha go out of combat before starting her dialogue with the ghost. I thought I’d include this since making Detha go ooc is still done by many many pugs.

Fix: ANet fixed it.

Awesome. Thanks for these tips.
