efgy007A few things to check:
- Are you using the off the grid lot trait in your saves? That's currently bugged, though I don't know that it should be causing issues in CAS. If so, go to the lot through manage worlds and remove the trait before trying to load the household.
- Have you tried moving the The Sims 4 folder out of documents to your desktop, to force the game to create a fresh user folder? (don't delete the old one; if a fresh folder works you'll want to try recovery of gallery/saves/rewards from the old files)
- Make sure all mods and cc are removed for testing. This includes things that you wouldn't think should affect the game (you'd be surprised the weird seemingly completely unrelated effects some things have).
