Sims 4 Wicked Whims Broken reports are exploding after the May 2026 update, with many players discovering that one of the game’s most popular mods is now causing Last Exception errors, UI glitches, infinite loading screens, and broken interactions after updating The Sims 4.
Honestly, if you have played The Sims 4 through enough patch days, this probably feels painfully familiar by now. Every major Sims update tends to break half the mod folder overnight, and Wicked Whims is almost always one of the first mods players rush to check after patches go live.
The Sims 4 May 2026 update has already caused issues for several major mods, including Better BuildBuy, TOOL Mod, MCCC, UI Cheats Extension, and More Columns.

Why Is Sims 4 Wicked Whims Broken?
The biggest reason Sims 4 Wicked Whims Broken issues happen after patches is because the mod relies heavily on scripts, animations, relationship systems, UI elements, and gameplay tuning.
Even small backend changes from EA can cause Wicked Whims to stop working properly until the creator releases a compatibility update.
Players are currently reporting:
- Wicked Whims interactions missing
- Infinite loading screens
- Broken relationship menus
- Last Exception errors
- CAS glitches
- Sims freezing
- Game crashes after loading households
Some players are also finding that their saves refuse to load at all while outdated Wicked Whims files remain installed.
How to Fix Sims 4 Wicked Whims Broken
The most important fix for Sims 4 Wicked Whims Broken issues is updating the mod itself.

- Remove all old Wicked Whims files
- Download the latest compatible version
- Delete localthumbcache.package
- Repair The Sims 4 through EA App or Steam
- Relaunch the game
If problems continue, temporarily test the game with only Wicked Whims installed before adding other mods back.
Sims 4 Wicked Whims Broken Could Be Caused by Other Mods
One of the frustrating things about Sims 4 patch days is that several broken mods often collide together at once.

- MCCC
- Better Exceptions
- UI Cheats Extension

It only takes a few seconds, but it fixes an incredible amount of weird Sims 4 behaviour after patches.
Seriously, if your game is acting cursed after updating mods, deleting that file should basically become muscle memory at this point.
Sims 4 Patch Days Always Turn Into Chaos
The Sims 4 modding community moves incredibly fast, but patch days are almost always messy for the first 24 to 48 hours.
Players rush to update mods, creators scramble to push compatibility fixes, and suddenly everyone is trying to work out whether:
- their save is broken
- their CC exploded
- or they just forgot to remove one outdated script file hidden somewhere deep in their Mods folder
Wicked Whims is simply one of the highest-profile mods affected this time around.
Sims 4 Wicked Whims Should Be Updated Soon
The good news is that major Sims 4 creators usually release updates fairly quickly after patches.
