Holiday on Repeat

@anneke33, yes I would have been able to help had I been on the computer at the time you posted, but I was doing other things at the time! 😃  Thankfully @RandomBuzziness  was able to help 🙌 so you didn't have to wait for me! 😳  And @RandomBuzziness  is correct in that @SheriGR is also very helpful !😇

@NiaraTiara, The best procedure is to move the Mods folder to your desktop, then delete the localthumbcache.package file like @RandomBuzziness mentioned. Also for extra safe measure is to Repair your game through Origin.  
Then you can add your Mods and CC back one by one, starting your game after adding each one to test each Mod or CC item.  But if you have a lot of CC, then you might want to do the 50/50 Method and test a larger batch of them at a time.  Once you find which Mod or CC is the culprit, you can then go back to whoever created it and see if they have an updated version (if they do, you can download that one).  If they don't have a new one, then you should just forget that Mod or CC as if they are never updated, they will continue to mess up your game! 😢

You should do this after each time your game acts up, especially after a patch is released by EA, as that is when a lot of Mods/CC become outdated!  We are getting a new Stuff Pack next week, so we will probably be getting a another patch from EA later this week!  You might want to wait until after that to complete your testing! 🤔

Please update us on if this fixes your problem or not! 😇

And @anneke33 , I was thinking before I saw your post that it was a shame that the broken holiday wasn't Groundhog Day! 😃  Love that movie! ❤️
