Ideas
Coming back because it's happened again in two separate save files. I don't remember where I moved to in one of them but it seemed to solve itself in that one when I sold something (I think, i have a terrible memory). However, it's happening again with every single attempt that I try to move my sims into the lot I want them to move into. It's the Yuma Heights lot in Oasis Springs. I've tried it with other sims, tried it with the household I play with being unplayed, but it doesn't seem to make a difference. I also then tried to move them into a different lot and it didn't seem to make a difference, whilst it didn't make them a millionaire, it did reduce the amount of money that they had from selling their furniture. They should've had 30,000 and instead got stuck with 7,000.
I've been trying to figure out a way to not make it happen for an hour!
