Players are reporting that The Sims 4 Mods and CC have completely broken with the Latest Update.
Today’s update, March 17th 2026, has reportedly completely broken all CC and Mods for some players. The patch today introduced The Sims 4 Marketplace, a storefront in which users can purchase Creator-made sets using the new in-game currency ‘Moola’. Updates that make major changes to the framework of the game usually break mods, notably UI mods. It seems this time the issue is a little bigger than that!

Player Reports Of Broken Mods And CC
Over on The Sims’ official Discord, players have been reporting various errors when playing with Mods and CC. Some are saying both CC and Mods have broken, some are reporting that just Mods are broken.
The last time there was a mass-breaking of CC was with the tattoos patch that was released before The Sims 4 Businesses & Hobbies. Despite players removing CC and Mods before updating, their games are still broken, even when mods are enabled in the settings. Community Manager Shawnee is responding to player feedback in The Sims Discord server, even suggesting that it is good practice to disable mods before updating, despite that not being the issue.
Reports Via Twitter and EA Forums
Other players have taken to X (formerly Twitter) to share their issues with the latest patch. As of wrigting there are no official patch notes for the update, so it is unknown where the issue stems from; however, it is likely related to how Marketplace Sets and Kits are now downloaded from the in-game marketplace.
so apparently this update is causing a lot of cc to not appear ingame…?

Create-A-Sim CC seems to be having issues deploying properly for those who can enter their game at all. This kind of issue is often caused by changes to meshes and textures.
Umm… folks…??

None of my CC or mods besides script mods load into the game after the update…?? pic.twitter.com/adkDe7A07e
Over on the official EA Forums, players have made reports and have received responses from staff that seem to indicate there is an error with.Package files, the file type that allows custom content and non-script mods to be read by the game.
Many .package mod files are not loading. Sorry, I don’t have more info than this right now. It seems likely that there’s an issue on the EA side. At the moment, please just hold off on trying to “fix” this yourself. It’s a good time to play mod-free or do something else. Modders are looking into at least finding a pattern to give you some helpful information, but it’s complex at the moment.
You can follow Broken and Updated Mods and CC to get info when I have more.
