this happened to Gromnir in nwn2, but it only happened in one place. after one of those qara battles outside the pub in nwn city we would get a similar overflow issue. however, were only an issue on that particular map... went elsewhere and no overflow. even so, that map were forever screwed.
HA! Good Fun!
Oh thanks ever for the cheery news. LOL
I'll have to see if it's popping up on other maps. Sounds like a re-install is in order then.
