Custom Content and mods can completely change how The Sims 4 feels, but when something breaks, it can be frustrating. This Sims 4 CC and Mods troubleshooting guide walks you through the most common problems and how to fix them step by step, using simple solutions that actually work.
If your CC is missing, mods stopped working after an update, or the game will not load properly, this guide will help you get everything running again.
Sims 4 CC and Mods Troubleshooting Guide: Step-by-Step Fixes
1. Check for Game Updates
Before anything else, make sure your game is fully updated. Outdated game versions are one of the main reasons mods stop working.
Open the EA App, go to your game library, right click on The Sims 4, and check for updates.
- Open EA App.
- Go to “My Game Library”.
- Right-click on The Sims 4 and select “Update Game”.
2. Verify CC and Mod Compatibility
Not all mods work forever. After major patches, creators usually need to update their files.
Visit the creator’s website or download page and confirm that your CC or mod is compatible with the current game version.
3. Enable Mods in Game Settings
Sometimes the problem is very simple.
Open The Sims 4, go to Options, Game Options, then Other. Make sure these options are checked:
- Enable Custom Content and Mods
- Script Mods Allowed
Restart the game after changing these settings.
4. Clear The Sims 4 Cache
Corrupted cache files can cause CC and mods to behave strangely.
Delete these files from your Sims 4 folder:
- localthumbcache.package
- cache
- cachestr
- onlinethumbnailcache
Clearing the cache does not delete saves or mods.
Please check here a fantastic guide by crinrict so you can do it properly.
5. Remove Duplicate CC and Mods
Duplicate files can cause conflicts and random issues.
Use a tool like The Sims 4 Mod Conflict Detector to scan your Mods folder and remove duplicates safely.
6. Test CC and Mods Individually
If you are not sure which file is causing problems, use the 50/50 method.
Move all your mods and CC out of the Mods folder. Add them back in small batches, launching the game each time. When the issue comes back, you have found the problematic file.
7. Check for Mod Conflicts
Some mods simply do not work well together.
Again, Mod Conflict Detector is very helpful here. If two mods conflict, remove one or look for an updated version.
8. Reinstall Broken CC or Mods
If one specific item is causing issues, reinstall it.
Delete the file completely, download it again from the original source, and place it back into your Mods folder.
9. Verify the Resource.cfg File
Your Resource.cfg file tells the game how deep it should read mod folders.
- Go to Documents, Electronic Arts, The Sims 4, Mods.
- Make sure the Resource.cfg file is present. If it is missing or edited incorrectly, CC may not load at all.
10. Check for Game Bugs
Sometimes the problem is not your CC.
Check the official Sims forums or EA Help to see if the issue is a known bug related to the current patch.
11. Back Up Saves and Reinstall the Game
If nothing else works, reinstalling the game may help.
Before doing this, back up:
- Saves folder
- Tray folder
- UserSetting.ini
After reinstalling, restore your files.
12. CC or Mods Not Showing Up at All
If nothing listed above worked for you and the cc still not showing up in your game, check out this video by Darielle with helpful tips. Watch video here.
Additional Tips:
- Always read the installation instructions provided by the mod/CC creator.
- Keep your mods and CC organized by categorizing them into folders within the
Modsfolder. - Regularly update your mods and CC to keep them compatible with the latest game patches.
By following these steps, you should be able to troubleshoot and resolve most issues with CC and Mods in The Sims 4.
Happy Simming!

FAQs About Sims 4 CC and Mods
Q1: Why is my Sims 4 CC not showing up in game?
This usually happens when mods are disabled in the game settings, the CC is placed too deep in the Mods folder, or the cache needs to be cleared. Always restart the game after enabling mods.
Q2: Do Sims 4 mods break after game updates?
Yes. Game updates often change how The Sims 4 works internally, which can cause mods and CC to stop working until creators release updated versions.
Q3: Should I remove mods before a Sims 4 update?
Yes, it is recommended to remove mods and CC before launching the game after an update. This helps prevent crashes, errors, and save file issues.
Q4: How can I tell which mod is causing problems?
The best way is to use the 50/50 method. Remove all mods, then add them back in small groups until the issue appears again. The last group added usually contains the broken file.
Q5: Where can I find updated Sims 4 mods and CC?
Updated versions are usually shared on creator websites, Patreon pages, ModTheSims, or through community updates on Twitter and Discord.
