Delurking to bawwww about crashes like everyone else.
My crashes usually happen a few human minutes into a new family if I play a household for a couple real hours and then switch to another household.
I delete cache.package files every time, it load-up crashes once then plays fine for awhile until the switch family crash. I also had it crash on me one time when I went to buy a rug. Again it was after playing a household for at least an hour my time.
Only other hack I have is censor removal, and it crashed before I put that in the same way it is now.
Not whining for you to solve my problems specifically, just adding to the information pool.
Unlike Sims2 crashes where it borked and dinged and then there was an error pop-up, Sims 3 just closes itself out.
