This just happened to me, May 2024. I don't understand. I added a couple of new mods, which are simple. I think the game updated and I go in there and hundreds of hours of gameplay is totally gone. I looked through your threads and haven't find anything that helped.
1. I have an older Mac.
2. I tried hitting "repair" didn't work.
3. I looked in my save folders, there are several saves there (up to 4?)
4. I do not have One Look.
5. I deleted the recently added mods to no avail.
6. I checked the Icloud settings, my Mac does not save Sims data to iCloud.
7. I checked how much space my Mac has, it has 93 gigs of space. Plenty.
8. I looked at the version, it ends in 12 something, not Legacy Version.
9. I am completely lost. Am I screwed?
i had the same thing too but i just rage quit and deleted everything :((
