Sims can't interact with certain objects- possible solution!!
I had started to have an issue where certain sims could not interact with certain object, certain sims couldn't gain relationships with new sims, couldn't switch to other sims, and at one point the thumbnails all switched to sims 2 (!)
Here is what was causing the problem!
I started with a family but wanted to get rid of a member so...
new game: I went into edit town, split the family, and evicted the unwanted sim by deleting from clipboard, went back into game (issues above)
New game: I turned on cheats and deleted the sim (issues above)
New game: The unwanted sim met an unfortunate fate in the pool in live mode (no problems!)
Getting rid of a sim by any means other then killing them off in live mode(😢)causes this problem. I thought it could be having puppies, but this was the issue.
I was playing with pets, supernatural, generations.
Hope this helps 🙂
