Corrupted House? Cannot load other lots or move households.
In only one save file, I am encountering a strange problem. I am able to load my one played household in their home, but if I try to travel with them, or go to any other lots, the lots all over various worlds are empty. They appear correctly in the map screen, but when they load up there is nothing there. One lot in San Myshuno also seemed to have its height set strangely, so that there is a giant hole in the world where part of the lot should be.
I am on generation 4 of a legacy, I really don't want to lose the family or their house. Being able to move out with my furniture would be an acceptable fallback, but that is giving an error also (see below)
Other save files seem unaffected.
I have tried:
- Removing all mods. Still happens.
- Repairing my game. Still happens.
- Recovering old versions of my saves using the in-game recovery and also using external backups. Still happens, going back several days.
- Resetting my game by renaming my "Sims 4" folder. Still happens
- Moving my sims out of their lot with their furniture: I get error 801, and after that point lots take infinitely long to attempt to load. Or sometimes crashes to desktop.
- Moving my sims to another save file using the library: The sims move over just fine, but when I try to place their lot from my library, it says "System Error" in red near the UI popover. It then gets stuck in an infinite loop of trying to place the house, and getting another system error.
