My saves keep losing custom-built lots - they revert to the base game default version, even though households/Sims data stays intact. This has now happened on my original save AND a brand new fresh save, so it's not isolated to one file.
What I've tried:
- Cleared all cache files (localthumbcache, cachestr, avatarcache, etc.)
- Fully reinstalled the game
- Created multiple fresh Sims 4 folders/saves
- Tested with Mods folder completely removed - issue persists
- Confirmed it's not CC-related since it happens with zero mods loaded
This also caused a related issue where apartment lots specifically became unopenable (error 801, walls up/down grayed out) in one world, which was fixed by starting a new save - but regular builds still keep reverting even on new saves.
Platform: Mac, 2024 MacBook Air, M3 chip, 16GB RAM
Has anyone else experienced builds reverting to default, or found a permanent fix?
