Re: [CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game
@hyunnie0205 No, don't touch the contents of the Delta folder. (If you already have moved these folders, delete the ones you moved and repair the game, which will restore the originals.) Delta contains data from patches, not the data for the packs themselves.
Did you only find one copy of each folder—the ones in Delta—and nothing anywhere else? If so, that means that you haven't installed the packs you're looking for. Please clear the EA App's cache:

Then go into the EA App's game library, click Sims 4, and select Manage > Manage Add-ons, then find the packs on the list and see whether you can download them. If not, let me know where you bought the codes for these packs.
