Guild Wars 2

Since the update detha has bugged out at the last room every single time for me.
She runs there and does nothing at the traps.

Getting her killed, porting etc doesnt work at all and I really dont feel like running the path all over again.

Replication of that problem: don’t know, we do the path as everyone does, even killed everything on the way one time. still bugged.

The bug has been around for a while and I don’t think anyone has been able to pinpoint the exact cause, although there are several good theories. There are a couple of things I do with my guild runs and we seem to manage to avoid getting stuck.

• In the hatchlings room, make sure the breeder dies before or close to the same time as the progress bar maxes for the number of hatchlings killed. If instead it looks like the breeder will survive and you fail the first attempt, make sure that everyone waypoints (so that Detha jumps with you) and, of course, kill that spawn of the breeder so the event itself can respawn.
• Once that event is done and you claim the ground chest, waypoint out together, again so that Detha stays with the group.
• As you run to the final (traps) room, try to stay together (so Detha stays with the group).
• When you enter the traps room, make sure no one goes into the big orange circle in the middle until Detha is there, too. You can do this by entering the room and heading towards one of the alcoves in the back. (Which alcove depends on which gate you used to enter.) Stay together until Detha joins you and then proceed together to the center where she will trigger the dialogue.

tl;dr kill breeder first (if poss), stay together as much as you can, and waypoint (together) so that Detha stays with you.

Of course, it shouldn’t bug at all. Instead of trying to fix it, ANet should change the trigger conditions so that it doesn’t matter how the group gets to the end.

Good luck.
