It is a specific kind of panic. You spend four hours building the perfect modern farmhouse in Willow Creek, you finally sit down to play, and then it hits you—the dreaded notification that the Wicked Whims script missing or is failing to load. Your Sims are standing there, stiff as boards, and the entire reason you modded the game in the first place is basically gone. It feels like the game is broken. Honestly, it kind of is.
But here is the thing: your files probably aren't "missing" in the sense that they vanished into the digital void. They are almost certainly just sitting in the wrong folder or being strangled by a specific setting you forgot to toggle after the last EA update. This happens to everyone. Whether you are a veteran player or just trying out TurboDriver’s work for the first time, the file structure of The Sims 4 is notoriously finicky.
The One Tiny Mistake Everyone Makes With Script Files
If you see the "Script File Missing" warning, the very first thing to check isn't your Downloads folder. It is your depth. I’m talking about folder nesting. The Sims 4 can read .package files if they are tucked away in subfolders, but script files—those .ts4script files that actually run the logic of the mod—are much more sensitive.
If you put the WickedWhims folder inside another folder called "Mods for Tuesday" which is inside your main "Mods" folder, the game will go blind. It cannot see that far down. Most experts and even TurboDriver himself recommend keeping script files no more than one folder deep.
Basically, the path should look like this: Documents > Electronic Arts > The Sims 4 > Mods > WickedWhimsMod. If you have a folder inside that folder containing the script, the engine just gives up. It’s a limitation of how Python scripts are injected into the game's simulation engine. Move those files up one level, and half the time, the error disappears instantly.
Why Every Update Breaks Your Mod Setup
EA likes to break things. Every time a new expansion pack like Lovestruck or a major base game patch drops, the game automatically disables all mods. This is a safety feature, but it’s also a major headache.
- Launch the game.
- Go to Game Options.
- Click on "Other."
- Make sure both "Enable Custom Content and Mods" AND "Script Mods Allowed" are checked.
If you forget that second box—the script mods one—the game will load your custom hair and furniture just fine, but the Wicked Whims script missing error will pop up because the "brain" of the mod is being blocked by the game's security settings. You have to restart the game after checking these boxes. No exceptions.
The Curse of the "Double Mod" and Old Files
Sometimes the script isn't missing; it’s just confused. If you have an old version of WickedWhims (or Heaven forbid, WonderfulWhims) sitting in a different folder, they will fight. This conflict leads to the game failing to initialize the script properly.
Search your Mods folder for "Wicked" and "Whims." If you see two different versions, delete them both. Start fresh. It is always better to do a clean install than to try and "patch" an old folder by dragging and dropping new files into it. Overwriting files in Windows or macOS sometimes leaves behind old garbage that causes "Last Exception" errors later on.
A Quick Reality Check on File Extensions
Check your extensions. I’ve seen players download the mod, and because their computer hides file extensions, they end up with a zipped folder inside their Mods folder. The Sims 4 cannot read a .zip or a .7z file. You must extract them.
Inside the official download, you should see two main files:
TSR4_WickedWhims_Scripts.ts4scriptTSR4_WickedWhims_Tuning.package
If you don't see that .ts4script file, your antivirus might have quarantined it. It sounds weird, but some aggressive antivirus software sees script injection files as "trojans" because of how they interact with other programs. Check your protection history if the file seems to disappear after you move it.

Dealing With OneDrive and iCloud Sync Issues
This is the silent killer of Sims 4 mods. If you are on Windows, OneDrive loves to "manage" your Documents folder. It will often move files to the cloud to save space, leaving a shortcut or a "ghost" file behind.
When The Sims 4 tries to launch, it looks for the mod, sees the file is actually in the cloud, and throws the Wicked Whims script missing error. To fix this, you really need to disable OneDrive syncing for your Electronic Arts folder. It’s a mess. Mac users deal with the same thing with iCloud Drive. If your "Documents" folder has a little cloud icon next to it, that’s your culprit.
How to Verify Your Mod is Actually Working
Once you think you've fixed it, don't just look for the "Mods" popup at the start of the game. That list is long and easy to misread. Instead, look for the "Wicked" tab when you click on a Sim or an object in-game.
If the "Wicked" menu appears but certain animations are missing, that is a different problem—you likely forgot to download animation packs. The script itself is the engine; the animations are the fuel. They are separate downloads. If the menu doesn't appear at all, the script is still not loading.
What About the "Incomplete Mod" Warning?
Sometimes the game says the mod is "Incomplete." This usually means you have the script file but deleted the tuning file. They are a matched set. They need each other. Always keep them in the same folder.
Actionable Steps for a Clean Fix
If you are staring at that error right now, follow this exact sequence. Don't skip a step because you think you already did it.
- Step 1: Delete the
localthumbcache.packagefile in yourThe Sims 4folder. This file stores "memory" of old mods and can keep the error active even after you've fixed the files. It's safe to delete; the game regenerates it. - Step 2: Delete your existing WickedWhims folder entirely.
- Step 3: Download the latest version directly from the official WickedWhims website or their Patreon. Do not use third-party "re-upload" sites; they are often outdated.
- Step 4: Extract the files using 7-Zip or WinRAR.
- Step 5: Place the folder
WickedWhimsModdirectly intoMods. - Step 6: Boot the game, toggle "Script Mods Allowed" off and then back on again, apply changes, and restart.
Following this path ensures that no old cache data is interfering with the new script injection. Most players find that deleting the localthumbcache.package is the "magic" step they were missing. It forces the game to look at your Mods folder with fresh eyes.
If the error persists after all this, the issue is likely a conflict with another "core" mod like MC Command Center or a UI Cheats extension that is also out of date. Ensure every script-based mod you use is compatible with the current game version. Keeping a tidy Mods folder isn't just about organization; it's the only way to keep the game playable in the long run.
