In the Lich lab, there's a large room with several (5 or 6?) Lichs and other monsters. You 'kill' the Lichs the first time, then they resurrect (as usual) but then turn into "statues" - they stop moving, you can't attack them. It's a largish room, with 2 doors into it, and you go down a few steps into the room. If need be, I can go back to the lab and get a more accurate location.I can't believe this hasn't been seen before - I had the problem the very first playthrough back in 2002, and every time since.
Could I have a corrupted CD??
btw for my original problem with Frosgard, I deleted the minisaves for Frosgard, and no more problem!!
