Well the last door is bugged also, if you die from the mouth and try to continue from the last checkpoint – you just can’t open the door for the basement. Rly nice!
On the point “escort researchers to the southern exit with Trahearne”, the researchers don’t want to follow me, no matter what I’m doing.
Tried this two times, have exactly the same result.
This quest definitely is bugged. You can jump down by the end mast, but my problem was that there isn’t any holes for filling?!? And you can spent all your life to kill ozzes.
