Ideas
I have the same issue, my sim is in university, every time her room mate is having her friend over (a celebrity) I get this last exception. I don't like playing with a save with last exceptions so I quit without saving and use a previous save, just for her to have him over again and me having the exception again. I don't play with mods.
