I'm not sure if this is a Bon Voyage problem or something else. I added a university to a neighborhood that I created and one of the things that I do is change the college students' appearance with Christianlov's Sim boutique. Prior to the sudden freezes/crashes I never had a problem with either the hack or BV.
The freezes/crashes occur when:
1. When I'm looking through the brown colored hair section ONLY. Everything is cool with the black, blonde and red. When I get to the third page of the brown hair section, it freezes. Wait long enough then it crashes. But freezes more often.
2. I did download some new items. About three new hair hairstyles, and a lot of outerwear. Most of the stuff I downloaded though appear only on adults not young adults.
I'm sure that I didn't try everything so suggestions are welcomed.
