Sim can't stop picking one thing multiple times.

Thought I fixed it... I did not... ever since I turned memory boost from auto to enabled, it hasn't stopped freaking out...

I turned off mods and it seemed to chill out but I'll need to check off a list and I'm too tired tonight... I'll try again tomorrow.

To make it wierder... my sim is in their house and they greet a random sim that didn't even appear until 10 seconds later to sit in the exact spot that he was greeting them at... and she didn't even get invited inside the house. I'm so confused...
