Guild Wars 2

I am doing this story line and I am at what I am pretty sure is the end or last leg. The quest says to help Trahearne escort everyone out of the south end of the cave. That goes off the map and I’m assuming ends the story. Well I rescued the group of researchers in the cave but instead of heading out of the southern exit everyone warped outside. Now they are square dancing waiting for something. None of them give any dialog options that continue the story. If I clear to the southern exit of the cave by myself there is a wall that looks destructible by Trahearne. I don’t really want to do this quest again So I’m sitting here hoping it will fix itself but I don’t know. If there something I should do?

Edit: the quest is in fact, forging the pact.

I’m having the exact same issue. Please resolve this! =C

I wormed my way though the Map and I’m outside now on the quest marker. It flashes but I don’t think that means anything.

Well I’ve spent a few hours in here. Im leaving now and I really don;t want to do this quest again so I’m hoping there is a fix for that.

The exact problem that is happening is even after clearing all risen from the personal story instance, the second research team will not follow you and Trembane out of they start point and to the southern exit.
trying talking to every one, searching the area, and going in to ever nook, cranny, and hole I could find to unglitch the NPC’s but they will not move.
Spent far to long on this missing, and would appreciate it being fixed so that we all can progress our story lines.
