jmblibra Did you test a new save in a clean Sims 4 folder, with nothing else added back? And did you repair the game before testing? If not, please do both now.
For your main save, it sounds like it's broken now, so please revert to a backup save and try again. If you can get a lastexception, I'd still like to see it. Here's how to load a backup save:
