How to Fix Problems with Mods/CC
http://www.carls-sims-4-guide.com/forum/index.php?topic=25031.msg426156#msg426156We recently received a new game patch that has made some game mods and custom content become outdated. You need to go through your mods folder to see what needs to be updated.
2. Create a new game save to see if you can recreate the issue.
3. Deactivate Origin In-Game - Open Origin, Go up to the Origin Menu, Click Origin and select Application Settings. Select the Origin In-Game tab. Make sure it is turned Off. - This deactivates Origin In-Game, as it has been known to cause problems with games.

5. Repair Game - In Origin, right-click on Sims 4 and select Repair. - Do note this repairs the game's install files, it does not make any changes to the saved game files. - Saved games are safe - won't be deleted.
6. Try a Sims 4 factory reset and a new game save without mods/cc.
