Re: why are all my sims 4 expansions pack and add on are missing?
@littlemetx21 Are you sure you're signed into the correct account? Since Sims 4 is free now, it's easy to create a new account and add the game to your library without realizing it. Please check your game library for the missing packs. If they show up as unowned, i.e. you're being asked to buy them again, check the inbox of the email address you're using to sign in to see whether it contains any receipts for EA purchases. If you don't find any, check your other email accounts as well.
If your content does show as owned but isn't loading in-game, please clear the cache for Origin or the EA App, whichever you're using:
https://help.ea.com/en/help/faq/clear-cache-to-fix-problems-with-your-games/
and repair the game: open your game library, right-click on the Sims 4 icon (Origin) or hover over the Sims 4 icon and click the three dots (EA App), and select Repair. If this doesn't help either, and you're using the EA App, please reinstall Origin and try repairing and launching the game from there.
And if you've bought any content from Steam, please let me know.
