Guild Wars 2

Jeffrey Vaughn.1793:

Try moving a ways away from him, then back. There’s a rare bug where he’ll think no players are around even though you’re standing right next to him. I believe a fix is slated for the 9/24 update.

Tried it. Didn’t work this the second time I’ve had to restart this quest with the same result.

I’m having the same problem with this quest. Get to the cave mouth kill all the Risen then Trahearne just stands there doing nothing. Pull mobs to him he fights them then goes back to standing in front of the cave.
