The Sims 4 mods and CC not working after the August 6 update can usually be explained by the game disabling custom content during the patch process or an installed mod no longer working correctly with the latest version. The August 6 release is a small hotfix and is expected to have minimal impact on mods, but players should still check their settings and test unconfirmed files carefully.
The hotfix changes systems involving manual saves, travelling, school schedules and careers. Mods connected to those areas deserve additional caution until their creators confirm compatibility, even though the update is not expected to cause the widespread disruption normally associated with a major expansion patch.
Why Are The Sims 4 Mods and CC Not Working After the August 6 Update?
The Sims 4 mods and CC not working after the August 6 update does not automatically mean every installed file is broken. The Sims 4 commonly disables custom content and script mods after a game update, meaning the files may still be inside the Mods folder but will not appear in gameplay.
Players must open Game Options, select Other and check whether Enable Custom Content and Mods is active. Anyone using script mods must also enable Script Mods Allowed.
The game needs to be fully restarted after either option is changed. Returning directly to a save without restarting may leave mods unavailable even though the correct boxes have been selected.
| Problem | Most likely first check |
|---|---|
| All mods and CC missing | Enable Custom Content and Mods |
| Script mods missing | Enable Script Mods Allowed |
| Mod menu appears but gameplay is broken | Check for updated mod versions |
| Game will not launch | Remove all mods and delete cache |
| One item looks broken | Remove or replace that CC file |
| Error appears after loading a household | Test gameplay mods using the 50/50 method |
How to Enable Mods After the August 6 Update
Players experiencing The Sims 4 mods and CC not working after the August 6 update should begin by checking the in-game settings.
Open The Sims 4 and select Game Options from the main menu. Choose Other and enable Custom Content and Mods. Enable Script Mods Allowed separately if script files are installed.
Apply the changes, close The Sims 4 completely and launch it again. The game should display a list of detected custom content during startup unless that notification has previously been disabled.
Do not immediately open an important save simply because the mod list appears. The menu only confirms that the game has detected the files. It does not confirm that every mod remains compatible with the new game version.
Are Mods Broken After The Sims 4 August 6 Update?
The Sims Team expects the August 6 hotfix to have minimal impact on mods and custom content. That means a widespread mod break is not expected, but individual files could still conflict with the updated game.
The August 6 patch fixes a memory crash during travel, manual saves overwriting the wrong slot, and stuck countdowns for school and careers. Custom careers, school overhauls, save-management tools, travel modifications and mods that change time or schedules should be treated cautiously until their creators confirm them as compatible.
Players should not label a mod as broken solely because it is missing after the update. Check that mods are enabled, restart the game and confirm that the file is installed in the correct folder before looking for a replacement.
Back Up Your Saves Before Testing Mods
Before fixing The Sims 4 mods and CC not working after the August 6 update, close the game and create a backup. PC and Mac players can copy the complete The Sims 4 folder found inside Documents and Electronic Arts.
Copying the entire folder protects saves, mods, Tray files, screenshots and other local content. Place the copy somewhere outside the Electronic Arts folder and rename it clearly so it cannot be confused with the active game folder.
Do not use an important save as a testing ground for unconfirmed mods. Create a disposable new game or use Save As to make a separate copy of the household before restoring custom content.
Saving a household while CC is removed can strip custom clothing, hair, furniture and other objects from the game. Exit without saving if an important household is accidentally loaded without its required files.
Delete the Localthumbcache File
An old cache file can retain information connected to mods that have been removed or replaced. After taking problematic mods out of the folder, delete the localthumbcache package file from The Sims 4 folder.
The game will create a new localthumbcache file the next time it launches. Removing this cache does not delete saved households, lots or gameplay progress.
The file should be deleted whenever gameplay or script mods are removed during troubleshooting. Leaving the old cache in place can make it appear that a removed mod is still affecting the game.
Test the Game With No Mods Installed
The quickest way to establish whether The Sims 4 mods and CC not working after the August 6 update is caused by custom files is to test the game with an empty Mods folder.
Close The Sims 4 and move the complete Mods folder to the desktop or another safe location. Delete localthumbcache and start the game again.
Create a temporary new save and test the feature that was failing. If the game works normally without mods, at least one file inside the removed folder is likely to be involved.
If the same problem continues in a fresh unmodded save, repair the game installation and confirm that the August 6 patch installed correctly. The problem may be connected to the game or installation rather than custom content.
Use the 50/50 Method to Find a Broken Mod
Players with large collections can use the 50/50 method to find the file causing The Sims 4 mods and CC not working after the August 6 update.
Begin with an empty Mods folder and divide the original collection into two groups. Add one half to the active Mods folder, delete localthumbcache and test the game.
If the problem returns, the faulty file is probably inside the half currently installed. If the game works, test the other half instead.
Continue dividing the problematic group into smaller sections until one mod remains. Keep notes on which files are included in each test so the same batch is not tested repeatedly.
Start with gameplay and script mods before testing ordinary cosmetic CC. Mods that alter menus, careers, school, travel, saves, time, traits or user-interface elements are generally more likely to cause functional errors than basic hair or clothing files.
How to Update Broken Sims 4 Mods
Visit the original creator’s official download page and check for a version released or confirmed after the August 6 patch. Do not download unofficial reuploads claiming to repair another creator’s work.
Remove the old mod before installing the replacement. Do not leave both versions in the Mods folder because duplicate files can cause conflicts even when the new version is compatible.
Read the creator’s installation instructions carefully. Some updates require additional files, while others require an older package to be removed completely.
Delete localthumbcache after replacing the mod and test it alone before restoring the remainder of the Mods folder.
What If Custom Content Is Missing From Sims and Lots?
The Sims 4 mods and CC not working after the August 6 update may leave Sims appearing bald, unclothed or covered in missing-texture patterns. Lots may also contain missing furniture or replaced objects.
Exit the game without saving. Check that Enable Custom Content and Mods is active, restart the game and confirm that the missing package files are still inside the Mods folder.
Do not save an established household while required CC is disabled. Saving can record the household or lot without those items, forcing the player to reapply them later.
If only one hair, outfit or object is affected, remove that individual file and check the creator’s page for an updated version. A single broken item does not mean the entire custom-content collection needs to be deleted.
What If Script Mods Still Do Not Appear?
Script mods require the separate Script Mods Allowed option. Check both mod settings, apply the changes and restart The Sims 4 completely.
Script files also need to be installed at an appropriate folder depth. A script mod buried inside too many subfolders may not be detected even though package-based CC appears normally.
Make sure the downloaded archive has been extracted correctly. Leaving the mod inside a compressed zip or rar file can prevent it from loading unless the creator specifically states otherwise.
What If The Sims 4 Will Not Open With Mods?
Remove every mod and custom-content file, delete localthumbcache and launch the game again. If it opens normally, restore mods in small batches until the file causing the launch failure is identified.
Players may encounter error codes connected to outdated script mods after an update. Errors including 102, 123, 125, 127, 129 or 131 can be connected to script problems, while error 110 commonly appears after game updates because of outdated mods.
Repair or verify The Sims 4 files if the game still fails to open with an empty Mods folder. EA app users can use Repair, while Steam and Epic Games Store players can verify the installation through their launcher.
Should You Remove All Mods Permanently?
The Sims 4 mods and CC not working after the August 6 update does not mean players need to permanently delete their complete collection. Moving the folder temporarily is safer because it preserves the original files while allowing an unmodded test.
Keep the removed folder outside The Sims 4 directory until creators have confirmed their mods as compatible, updated or broken. Restore confirmed files gradually rather than returning thousands of items at once.
The August 6 hotfix is expected to have only a limited effect on mods. Checking the settings, backing up saves, deleting localthumbcache and testing gameplay mods carefully should resolve most cases of The Sims 4 mods and CC not working after the August 6 update without sacrificing an entire custom-content library.
