How to Find Broken CC in Sims 4 safely: back up Saves, Tray and Mods, move custom content outside the active Sims 4 folder, clear localthumbcache.package and test in a new save. If the glitch disappears, use the 50/50 method to narrow down the problem file without deleting your whole collection.
Never save over a favourite household while its custom content is removed: missing items may disappear from that save. Test in a disposable save or exit without saving, and restore your original files only after checking the creator’s compatible update.
The May 2026 update introduced major changes involving:
- Create-A-Sim base layers
- interface systems
- gameplay fixes
- save functionality
- CAS layering
Because of those changes, older CC files are now conflicting with the updated game systems, especially CAS-related content.
Here is exactly how to find broken CC in Sims 4 after the latest update, including the best methods, tools, and fixes players can use to clean up their mods folder safely.
Why CC Breaks After Sims 4 Updates
How to find broken CC in Sims 4 after the latest update starts with understanding why this happens so often.
Whenever EA changes:
- Create-A-Sim systems
- clothing layers
- UI systems
- textures
- interactions
older CC can stop functioning correctly.
The latest Sims 4 patch especially affected:
- clothing CC
- accessories
- overlays
- makeup
- skin details
- CAS presets
because of the new base layer system added to Create-A-Sim.
Signs You Have Broken CC in Sims 4
Players searching how to find broken CC in Sims 4 after the latest update are usually dealing with:
- Sims appearing invisible
- giant red and white question marks
- broken textures
- distorted clothing
- missing thumbnails
- blacked-out Sims
- infinite loading screens
- CAS freezing
- random crashes
Sometimes the game still launches normally while the CC itself is broken underneath.
Honestly, the random cursed-looking Sims screenshots after patch day are basically a Sims community tradition at this point.
How to Find Broken CC in Sims 4 with the 50/50 method
The safest way for how to find broken CC in Sims 4 after the latest update is using the:
- 50/50 method
This works by:
- Removing half your CC
- Testing the game
- Narrowing down the broken section
- Repeating until the broken file is found
While it takes time, it is still one of the most reliable methods for finding broken Sims 4 custom content.
Especially for players with:
- huge CC folders
- thousands of files
- years of downloads
- mixed creator content
Better Exceptions Can Help Identify Broken CC
One of the most useful tools for how to find broken CC in Sims 4 after the latest update is:
- Better Exceptions
This mod helps detect:
- broken CC
- script conflicts
- UI problems
- outdated mods
- interaction errors
After major updates, Better Exceptions becomes incredibly useful for narrowing down problem files quickly.
Sims 4 Tray Importer Can Help Too
Another useful tool is:
- Sims 4 Tray Importer
Players can use it to:
- locate CC attached to households
- identify broken CAS items
- remove unwanted content
- track missing files
This is especially useful if only certain Sims or outfits appear broken after the update.
Delete localthumbcache.package
One of the biggest fixes players forget during how to find broken CC in Sims 4 after the latest update is deleting:
- localthumbcache.package
This cache file stores old mod and CC data that often conflicts with updated game systems.
Leaving it behind can cause:
- texture issues

- outdated CAS data
Long-time Sims players honestly delete it automatically after every patch now.
The New Base Layer System Is Breaking Older CAS CC
The May 2026 update added new:
- base layers
- clothing layering systems
- CAS customisation options
While these changes are genuinely useful, they also appear to be conflicting heavily with older CAS custom content.
This is especially affecting:
- overlays
- underwear replacements
- accessories
- layered clothing mods
- body presets
Creators are already beginning to update affected content.
Avoid Loading Important Saves While Testing CC
If you are still troubleshooting how to find broken CC in Sims 4 after the latest update, avoid opening:
- legacy saves

- heavily modded households
- important gameplay worlds
Broken CC can sometimes create:

For How to Find Broken CC in Sims 4, halve the group that still produces the bug and test only that half. Keep splitting the failing group until you identify a single file. If neither half causes the glitch alone, test combinations of files for a conflict. Record each group and never overwrite your untouched backup.
