Another "my game is crashing" post

I read through quite a bit of them but I have unanswered questions. First I'll explain whats happening. I haven't tried any other lots because I'm sure this one is the problem. I have a particular lot which i just played last night and purchased some new outfits i downloaded. Afterwards, if i clicked on the dressers the Plan Outfit option had everything except "Everyday". I have a hacked shopping rack that lets you buy clothes, then kicks in to the plan outfit option right after and that still worked so i was able to change outfits. I finished playing and when i tried loading the game tonight the typical application terminating box comes up.

I've read about deleting the groups.cache(i think thats what its called) and it did nothing. I have quite abit of custom content, I saw a post that said to take out what was downloaded more recently so ill probably try that.

I'm worried that if i move a folder with downloads that my sim is using (such as hair i downloaded or worse, custom eyes that i cant just select from "change appearance") since that hair is no longer available, what will happen to my sim? will it dissapear when i reload the game? or will the hair just set back to a maxis default.

I'm sorry if i could have found these answers by searching posts but i promise i really did look..there were just so many yet no one said what happens to sims after content is deleted or moved.
