@aodoherty, when you started having this problem, did you test this without your Mods/CC?🤔 While this could be a bug, we have had a lot of updates since last August and some of your Mods or CC could now be outdated. You would need to get the most recent version of any outdated Mod or CC. Also, sometimes bits of corrupted data can linger, so it is best to do the following :
1) Move the Mods Folder to your desktop
2) Delete localthumbcache.package file in the game folder.
3) Fix you game in Origin by logging in and go to Library, then right-click on The Sims 4 and choose the "Repair Game" option from the list. Wait until Origin finishes repairing all your packs and not just the base game.
4) Now, when you turn on your game again, it will create a new mods folder that will be empty. Check to see if your game is now working without mods/CC.
5) Now you can try adding back items from your Mods folder one at a time checking your game each time to see which item is causing your game to not work properly. If you have a lot of items, you can try the 50/50 Method.
The CC creators will usually update the CC items and Mods after these updates, so when you find out which one is the culprit, you can get the updated version from whoever made that item of CC in the first place. You should try these steps any time you have problems in your game to rule out CC/Mods problems. It is the responsibility of the Mods/CC creators to update their items anytime EA releases a patch/update, and it is the responsibility of the people who use Mods/CC to make sure they are using the most recent version.
If you try the steps listed above and still have the same problems, then it might be a bug. But we need to rule out any outdated Mods/CC problems first! 🙂
Please update us on if this helps your problem or not! 😇
