Yeah, it's bad... almost done with the final battle, had a decent chance to win it...crash when a dragon is trying to take a turn. I guess I won't retry until a patch that addresses this issue.
Edit: A bit more info on this. I insanely kept trying the final battle over and over (I guess I was kind of enjoying trying different tactics and such), and every time I got near the end it would crash. It was a very long battle too, so I'm surprised I had the patience to stick with it. I almost gave up to wait for the next patch many times. The vampires were crashing just about every time they acted. Finally I got through a round where 1 vampire didn't crash, and I took out the other before he acted, then took out the first vampire right after that so he didn't get a 2nd chance. I had the black dragon wizard disabled (force cage?) and so he wasn't acting and didn't crash either. One thing I noticed, which may be a factor, the vampire always crashed when I had the hallway where he enters silenced, so he was trying to do something other than casting a spell, maybe using an ability (or maybe trying to cast a silenced spell if he is able to). When, instead of silencing that area, I managed to kill off or disable all of the psi/casters who enter there by other means, the vampire got his spells off normally and then I killed him shortly thereafter. But I don't know for sure if the silence was a factor or it was just luck.
