Guild Wars 2

Having same problem, Trahearn has not died and is in cave with 2nd group of researchers. I have cleared the mobs with 2nd group of researchers. I do the dialong with Kekt, and say to get going. Agent Zrii and crusader Afanan are there, and the 2nd group I started out to attack nearest mob and all joined in on battle, but as I progress through dungeon, only Trahearn will follow, the other stay in the enclave where the 2nd group was found. I made it to the southern exit with Trahearn and there is no dialog there that helps. He says in effect, he thinks he can get us out if I protect him.
Well at the blocked exit and only Trahearn followed me. I went back to the researchers and tried a dialog with Kekt again, but none of them including Zrii and Afanen will follow, This is still bugged, I am lvl 80. wasn’t able to get this far earlier before todays patch. the 2nd group of researchers were portaling out of the cave near the start. So there is an improvement but still bugged and can’t continue.

Similiar problem, I have rescued the 2nd team, they teleported out of the cave and were all did for some reason. Southern entrance is blocked. I went out the cave and found 2nd team and Traherne, all dead, managed to get everyone alive and Traherne says: I believe I can get us out of here, all I need is your protection while I summon help.
They won’t move. no enemy around them, all alive, If I move they don’t, no enemy on the way to cave entrance, cave 90% clear and clear to the southern entrance. This is still bugged. They don’t move at all.
