Re: [CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game
@ShatoraDragon If you have the CAS Demo installed, please see this thread:
Otherwise, please run searches for two or three of your missing packs. Open a File Explorer window, click This PC in the left panel, and enter the folder name for one of the missing packs in the search field in the upper-right corner. This is the full list of packs:

For example, if you're looking for Seasons, you'd search for EP05 . Wait for the search to finish, then make sure the full file path is showing under each result. If it's not, expand the window sideways as necessary. Take a screenshot using Windows key-shift-S and attach it to a reply here. Then repeat for one or two more packs.
For the missing items, you may need to recover a backup save after restoring the packs' data.
