When a Sim graduates, regardless of whether there was a graduation party or just called a cab, or used newspaper to find new place,  and regardless of whether its a Greek house, dorm or house...the first Sim gets in the cab to move out and all playable Sims on the lot jump in with them, leaving an empty house behind.

The only solution I've found is with Insiminator hacks by making the moving out Sim "unselectable" then using the family tree to "remove from family as townie". Not even putting a fence or wall around the other Sims helps. Having a guest over and making the guest selectable before everyone climbs in the cab has worked. I can then summon the others back that shouldn't have left.

Anyone have a solution to this annoying problem or I am the only that's ever had this happen?

Every sim in my neighborhood- including neighborhoods I haven't played in months- were all "unknown." Their indivual images were all potato heads. I have no idea how this could have happened- no power failures or game crashes, nothing weird while saving or shutting down the game.

I tried uninstalling SimPE and redownloading it which did not help at all.

Could it be a strange side effect of something I downloaded?

I've had a couple of servos "run amock" and then just slump over backwards. In this broken state, the only interaction option other Sims have is "repair" (and "selectable" because of Insiminator). However, when another Sim is instructed to repair the servo, the order falls out of queue and the Sim does nothing. This is true even of a Sim with a gold badge in robot repair. Is there any way to reactivate the servo or is it doomed to be lawn ornament?

Apologies if this iscovered elsewhere, but if so, I couldn't find it. After installing Uni, NTL, and OFB, I noticed that SIMs no longer change into tuxes and wedding gowns during wedding arch weddings.
 
Is this a bug, something Maxis changed, (to allow more customization) or something I have downloaded and can't find to fix?
