@SummerSloane Does it only happen after you've added the script mods back in then taken them out again? Or does it happen before you've added them back in, after playing a clean game for a while?
If the issue is related to Monterey you will need to wait for either EA to fix it, or for a future Apple update which may change whatever the trigger is.
If it's Mod related you need to test adding them back in one at a time, finding out the culprit.
I suspect it is a mixture of these two things. With regards to the Mac, the more content you add to your game the more your Mac will struggle to run it. It is difficult to sometimes troubleshoot on low spec machines because performance will always be compromised.
I would try a clean folder again and play it for several hours without adding in any of your Mods, see if it happens again and how frequently.
