I made a new car and while testing it i tried to woohoo.....
The result was that both sims had a reset to the lot entrance and both were invisible...
First thing i did was take a maxis default car and try again(on a diffrent lot)
Again both became invisible.....
I suspect this is a Free time bug?
Any one else had this problem?
I played on the new neighborhood that came with freetime and have only the insimenator installed.
