yeahh, i deleted everything CLEAN and tried it on my sisters laptop as well and she didnt even have a single file on house party. i thought, oh, maybe its an update bug. then after this, im starting to think so. and its on everything. it occurs only during story mode black guy isnt there and everythings like a ghost house instead of a party house
EDIT. i dunno how, but loaded one of the side stories and the characters loaded, went back to the main story and everything was fine....dunno what was that all about but..okay.
