I'm still interested in this. I think I've tried with Catalysts 9.1-9.3 over the months and still have the problem (we should be up to 9.5 or 9.6 now so I guess I could try them?) and I don't think it's a driver problem.
I don't want to start Requiem without getting all the story from Black Plague, and other than this both Overture and Black Plague were pretty much bug free for me (maybe a crash to desktop once or twice in Overture iirc).
Overall it sounds exactly like the Mess Hall crash but in a different location so hopefully this thread
http://www.frictionalgames.com/forum/sho...p?tid=2931 will eventually fix our problem too.
Are all three of us on Vista 64 + ATI?
