Crashing east of Beregost, assertion failed, black screen Options

[Bombur]

Hey Vlad et al.,

In my installation, the area east of Beregost (where the Morning Lord's temple is) kills the game. The area loads fine. But when I start walking around, I get a black screen. If I kill the process and restart, I get the same thing. Here's the error from the Baldur.err file:

ASSERTION FAILED!
File: ObjCreature.cpp
Line: 12162

Exp: pCreature != NULL && creatureSize > 0

Msg: no msg.
Run Debugger?

I'm guessing this isn't a standard bug or it would have been mentioned somewhere. I searched the forums for the line number and found nothing.

I'm running on Windows 10 Pro under compatibility mode. I have a bare minimum game install (BG2/ToB + patch + BD1.75 + TS7.06 + NEJ7.02).

Any suggestions on an easy resolve? And by "easy," I'm hoping for something other than a total rebuild. ;-)

Thanks!
