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?

I have never heard of this problem, I do not think it is a bug with the game itself.. do you have a lot of Mods (aside from the Insimenator)? Try removing all game mods and go to Uni and try to let someone graduate - if the problem goes away, you know it's an issue with one of the mods. If it persists.. then you have some more debugging to do!

Sounds like a incompatible mod to me.

It is - I had this problem once, ages ago. The clothing globals from JM's clothing tool was the culprit - it doesn't play nice with Inteen. Get rid of it and they'll be fine.

I'm not certain if I have the JM clothign tool, but thanks for the replies.  I have noticed that if I use the "temporal adjustor" and age a student to adult, then no one gets in the cab with them.

I have the same problem.. when I select a sim to go dw others in the house come too, I thought it was part of the game.
