You will also need to delete your localthumbcache.package to get rid of any corrupted bits that have remained behind! You will need to find which Mods or CC items are causing the problems and then go back to where you downloaded them from and see if they have any newer versions that are compatible with the most recent game patch, which was at the end of last month. Anytime there is a new patch for the game there is a chance that some Mods/CC will become outdated/broken. I once met a person whose CC eyelashes caused her Sims not to go to work! While the game allows Mods/CC it was not made around it. Although it often seems odd, sometimes even If your Mod or CC doesn't' seem to have to do with going to work or school, it can still cause problems. thank you for telling us you use Mods and CC.
