After fighting through STUPID amounts of undead (seriously in a long mission with no repair stuff or anything), we end up here with the people we’re supposed to escort magically teleported out of the cave and we found them dead surrounded by enemies. The way we’re supposed to go out (southern exit which is past even more enemies) is blocked so we can’t even get there to trigger the cutscene.
Reported it in-game and also reporting it here. See the picture for an illustration via the map including white dots showing where we went.
