UWE bug with Bele'coz

Playing around with the mod UWE, so far loving it and the added challenge it brings to the game. Sadly there is a major game-breaking bug in where I'd you defeat the Bele'coz faction and pickup their leader, if you then approach the vicinity of Admag then the game will freeze and crash... As if there is some sort of conflict between Admag and the Bele'coz leader.

As I'm only using the UWE mod, it's not a mod conflict causing the crass but something to do with the Bele'coz faction.
