I bought and downloaded 2 of the latest kits, The game has not recognised them.

@StormzyBby19  Please clear the EA App's cache:

https://help.ea.com/en-us/help/faq/clear-cache-to-fix-problems-with-your-games/

and repair the game (Sims 4 > Manage > Repair).

If that doesn't help, let me know whether your computer runs Windows or macOS and whether the EA App still thinks these packs are installed.

Nope, that hasn't worked. I still can't see the kits or the items in them. I use windows 11, It says the packs are installed but the kits don't show up in my game.

@StormzyBby19  Please run a search for each of your missing kits.  These are their folder names:

SP58: Comfy Gamer

SP59: Secret Sanctuary

SP60: Casanova Cave

So if you're looking for Secret Sanctuary, search for SP59 .  Open a File Explorer window, click This PC in the left panel, and enter SP59 in the search field in the upper-right corner.  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.

Do the same for the other kit.  Finally, do this for a pack that IS loading, for example EP01 is Get to Work, and EP05 is Seasons.

I have attached the screenshots down below, they are in the correct installation paths I think. The only thing I can see that is different with the SP's is that there is no Delta on the end of the folder unlike the EP that I tried which does have that.

@StormzyBby19  That looks fine.  I should have asked for clarification before, but are all the items from each pack missing, or only some?  I thought all since you said the game didn't recognize the kits, but maybe I got that wrong.  The reason I ask is that clutter items missing is a known bug after the patch:

https://answers.ea.com/t5/Bug-Reports/Clutter-items-not-showing-up-in-Build-Buy/td-p/14393957

But if nothing from either pack is loading, that's a separate issue.

Hi! Thank you for your help, while the actual kit names aren't showing up on the list of packs you have in the game, at least I can access the premade room for the items of it. 

@StormzyBby19  Then do you think you have the issue in the bug report?  I can merge your posts if so.  Otherwise, I would try deleting one of the kits' folders, one directly in "The Sims 4" rather than in the Installer folder, and reinstalling it.  You'd need to close the EA App and kill the EABackgroundService in the Task Manager first.

Hi! I had the exact same problem!

Here's how I fixed it:

1) Go to the EA app

2) Go to Sims 4 page

3) Go to Add-ons page at the top of the page

4) Scroll down to the Kits section

5) Click on the Kits in question

6) Click download on each missing Kit

7) Run game like normal

I had to manually download lilsimsie's, Bella Goth's, and Don Lothario's kits. They didn't download automatically like they normally would.

I hope that helps! ❤️
