Who should use this method?
Anyone who installs premium content from the Sims 3 Store can use this method to repair their ccmerged.package. Even if you have never deleted anything in your DCBackup folder, your ccmerged.package may have somehow become corrupt or incomplete if the Launcher had trouble merging the information. Errors with the Deep Fryer and Ice Cream Maker, the sauna, moodlets, sims resetting, sims not gaining gambling skill, being unable to use the wood fire oven/teppanyaki grill/etc., are all linked to the ccmerged.package. This is probably also why the store development team is not able to reproduce the errors: their ccmerged.package is complete. It’s also why the SimGurus may simply tell you to re-install the object.
