UI Cheats not working in The Sims 4

Panels broke after a game patch
Each build is made for one patch. v1.59.1 was made for 1.127.41, and the game has been on 1.129.39 since 27 October 2026.
Right-click the notebook icon to see which version loaded. If it's older than v1.59.1, install the current build. If it's current and that patch broke your panels, type your cheats until weerbesu's next release.
Right-clicking does nothing anywhere
In Game Options, Other, tick Enable Custom Content and Mods and Script Mods Allowed, then restart the game.
Both files should now show in the in-game Mods menu. If not, extract the zip into your Mods folder.
A box opens but your number does nothing
Your script file isn't loading. Check it's no more than one subfolder inside Mods.
It's loaded once it shows under Script Mods in the Mods menu. If not, check Script Mods Allowed and restart.
Two copies of the mod are installed
Delete every copy except the current pair, including backups and anything you renamed.
Search the Mods folder for "ui_cheats" and expect exactly two files. If deleted files come back, check OneDrive (see rarer causes).
It stopped when you added another UI mod
Move your other mods out and start the game with UI Cheats on its own.
If it works alone, add the rest back a few at a time until it breaks again. If it fails alone, try the cache.
Panels look wrong right after an update
Close the game and delete localthumbcache.package from Documents, Electronic Arts, The Sims 4.
The game rebuilds it on the next launch. If panels still look wrong, go back to the version check.
Recent issues
Marketplace pictures, and what weerbesu and EA have said
If Marketplace pictures look wrong, type clearonlinethumbnailcache true in the cheat console (added in patch 1.127.41). It's listed with the other interface and cache commands.
weerbesu's replies on Sim Profile and aspiration cheats are from 30 October and 3 November 2026. He says they still work for him in the latest version of the game, and he doesn't name a patch. He also says his recent Wants pinning fix clashes with some UI mods, so run the same test. He plans a fallback for that clash, which hasn't shipped yet.
EA's notes for patch 1.128.90 say the expanded Buff panel no longer closes at 2x speed or above, and add: "UI mods that replace the Buff panel or time controls may need to account for this behavior."
UI Cheats touches both (moodlets and the clock), so watch for a new build, though EA isn't saying UI Cheats breaks.
EA's notes for 1.129.39 have no section for modders and don't name UI Cheats. They do link many top crash reports to outdated or conflicting mod files, and point players to EA's guide to mods and game updates.
Symptom and fix at a glance
| What you see | Usual cause | First thing to try |
|---|---|---|
| Panels missing, text or graphics wrong, menus freezing after a patch | Game version and mod version don't match | Install the mod build made for your game patch |
| A box opens, but entering a value does nothing | The script file isn't loading | Check folder depth and Script Mods Allowed, then restart |
| Right-click does nothing anywhere | Neither file loaded, or mods are switched off | Tick both options in Game Options, Other, and restart |
| Nothing appears in the Mods menu | The zip was never extracted, or the files are in the wrong folder | Extract the archive into the Documents Mods folder |
| It worked, then stopped after you added another mod | Another user interface mod overriding the same resources | Test alone, then add the other UI mods back one at a time |
| Only Sim Profile or aspiration cheats fail | Probably a conflicting UI mod, weerbesu says | Test with only UI Cheats in the Mods folder |
| Odd behavior right after an update | Stale cached data | Delete localthumbcache.package and relaunch |
| Mods folder ignored entirely, deleted files reappear | Documents redirected into OneDrive on Windows | Move Electronic Arts to a local drive or exclude it from sync |
| Two versions of the mod in the folder | Duplicate or renamed copies | Delete everything except the current pair of files |
Getting help
If the cheat console itself is what broke, that's a different problem: Sims 4 cheats not working.
Typed cheats don't need the mod, so you can use needs cheats, skill cheats, career cheats and relationship cheats while you sort it out.
Rarer causes, and fixes you can skip
On Windows, OneDrive can take over your Documents folder. The game then reads a different Electronic Arts folder from the one you're editing, and files you delete come back. Move the Electronic Arts folder to a local drive, or exclude The Sims 4 folders from sync. That one comes from EA Forums reports rather than the author.
The game only reads Documents\Electronic Arts\The Sims 4\Mods. Steam players sometimes put mods in the Steam install directory, which doesn't work. Mac paths are on the Mac install guide. Also check you're in Live mode, because most of the panels the mod extends only exist there.
If you have a Last Exception or Better Exceptions file, we couldn't find anything on reading one for this mod. Remove mods until the file stops appearing, then report that mod to whoever wrote it.
Don't rebuild Resource.cfg by hand. A missing one was a real problem years ago, but current versions of The Sims 4 handle mod discovery themselves and put the file back. That's from community guides rather than EA, though they agree on it.
Reinstalling The Sims 4 won't help. The mod is two files in a folder the game reads at launch, and nothing in the author's troubleshooting points at a reinstall.
Going back a version won't help either. The release post carries one current build, so downgrading means taking a copy from a site that isn't the author's. Legacy Edition is the exception, and it's a separate frozen build.
Your saves aren't the problem, so leave them alone and fix the versions. The only save issue on record was an aspiration cheat bug fixed in v1.16.2 in January 2020.
You don't need testingcheats for the mod either. It stopped needing that in v1.1, back in 2015, so if nothing happens when you click, look at the installation.
Frequently asked questions
The cheat box appears, but typing a number does nothing. What is wrong?
Your package file loaded and your script file didn't, which is the author's own diagnosis. Check that the .ts4script file is no more than one subfolder inside Mods, and that Script Mods Allowed is on and you've restarted since. The Mods menu tells you when it's fixed, because the file shows up under Script Mods.
Does every Sims 4 patch break UI Cheats?
A patch can, because each build is made for one game patch, and the author says a mismatch is behind every case of missing panels and frozen menus. v1.59.1 was built for 1.127.41 and the game is on 1.129.39, which weerbesu hasn't confirmed for this build yet. The version history shows when a new build lands.
Can another mod conflict with UI Cheats?
Only another user interface mod that overrides the same resources. The author says script mods and tuning mods don't conflict. Two independent guides report MC Command Center running alongside it, as UI Cheats vs MCCC explains.
