I'm playing on an older PC with Windows Vista 64bit and with all service packes, in XP mode. I have played G2 NotR Ch2 a few times and never met this problem.

What happens is: I am on the Castle side of the river, killing the lurkers for Geppert's friend, I can't recall his name now. So, with every one of the lurkers in this area the following happened.

the lurker noticed me, growled etc and then began to walk towards me. Suddenly (even on level ground) it stopped and just stood there, frozen. I had to come near it and hit it. Immediately it unfroze and attacked me. This happened, as I said, with all the lurkers in that particular area.

I exited the game, and then replayed the area: same thing.

When I moved on to other areas, all was well, except with one bloodfly, but things sometimes do go funny with bloodflies and other flying beasts, so not unusual.

As I say, I've played this part of VoM at least twice before, on the same PC, and never run into this problem with the lurkers (or other walking beasts).

Thank you for any help you can give me.
