I take that back. I also crash in the Raduta Keep area now, never used to though. This seems to be caused by something completely different than the Balinoks crash though and appears to affects a much larger portion of the playerbase, our entire party had the same issues. Also unlike the Balinoks crash this does not appear to be graphics related, changing your video settings seems to have absolutely no effect. Some players crash when entering the area and others when leaving it, some crash in both directions.
Anyway, I created a bug report thread about it. As the bug appears to be universal or incredibly common, I highly doubt it is related to anyone's tech specifications or game settings.
