Re: The Sims CC preview problem.
@thesimssireYou should also delete the 'localthumbcache.package' in The Sims folder in which you find the Mods folder. Usually the bad cc gets stuck in this file too. So when you delete it the game will refresh it automatically.
Nevertheless old cc can cause a lot of problems too. So please, always check if there is an update available after every patchupdate of The Sims.
Have fun playing 😏
