I had to come out of lurkingdom to tell of the bug I've found.  I have a family of 3 roomates that are pretty much unplayable due to a jump/freeze bug.  Invisi-sims with only footprints visible before they "jumped" outside, and objects saying that a sim is currently using them when they aren't.  The rest of the town had some issues too. 

This is what happened to my sleeping sim.......




At the library......




Some sort of Vulcan body meld???..........
