I've never had this occur in my game that I can recall. But it strikes me that you could go into build mode, save the lot itself. Exit the lot to get into map mode. Evict your family. Then place the now saved version from your My Library. Via map mode go into build mode, change the lot designation and then move your family back in. That way, I hope, your Sims' things, furniture, etc. should be intact. I save lots I've built and furnished through build mode all of the time. Then I place them when I'm ready for them. Good luck and what a strange thing to have happen in your game. I know I've managed to lose a window in between gaming sessions. :open_mouth: Didn't realize it until after I snapped a screenshot of the house.
