Guild Wars 2

There’s an objective that tells you to investigate some broken gates in the sewers of Lions Arch, it’s the second last one in this quest.
The problem is that it never triggers as complete even after you’ve done the objective that comes after it.

Just encountered this bug…seems as if this quest is quite buggy.
Experienced the problem you encountered as well as another when I restarted the quest in which the second objective about finding the missing gaurdsmen didn’t trigger as I rushed through the quest triggering Forgal to leave on his Cutscene but no completion of quest

It happened to me, too. I even got to the cutscene in which Forgal tells me to meet him on Claw Island, but then the instance doesn’t end and if I leave I have to do it again.

It worked for me on the second try, though. I believe the bug has to do with Forgal not moving properly.

Just completed this quest myself, and while I had no problems with objectives updating, I did have problems with Forgal disappearing into the walls of the sewers constantly, and sometimes pushing enemies beyond the walls of the sewers as well.

Finally completed the quest…forgal disapeared most of the entire level and re-appeared during the undead scout fight…needs to be fixed for future players.
