Sims won't interact with objects; CC works individually, but not all together.

Currently having an issue where my sims won't interact with any objects. Every time I try to get them to do anything, they stick their arms out to the side and then do nothing. Actions either queue and don't work, or don't queue at all. They previously weren't interacting with each other, but that stopped after I tried the solution in this post.

This started when I installed some new CC and my game wouldn't start up at all. Did the 50% method, but there was no issue with the CC individually, only all together. So I assumed there was a conflict with some of the new CC, and just deleted all the CC I downloaded that day. So now there's no new CC in my game; but the game still isn't working. Tried the 50% method again, and the same issue - the CC works individually, but all together, it causes an issue. Except these are the same mods that were working the day before. There's nothing new in my game because I deleted all the new stuff I had downloaded.

I've tried sims.hard_reset. I've tried evicting my sims, moving them into another lot, and then moving them back into their original one (This solved them not interacting with each other, but they still won't interact with objects). I've restarted my computer, I've repaired my game using origin, but to no avail.

I'm using Windows 7, my game is updated to the latest patch. Thank you!
