By doing the maintenance you can find out which Mods/CC are causing problems and you can also get rid of some of the corrupted bits of data that might remain (which a bad Mod/CC detection program will not do!)Ģ) Delete localthumbcache.package file in the game folder.ģ) 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. We just had an update to the game, and anytime the game has an update there is a chance that Mods and CC can become outdated and cause problems. anytime you have a problem with your game and use Mods/CC you should do some Mods/CC maintenance.
