The Sims 4 Script Call Failed error usually appears when you try to place or use an object in Build Mode, and it often means that a mod, custom content item or game file is no longer working correctly.
Instead of placing the selected item, the game may display a red Script Call Failed message. The error can affect custom content, ordinary furniture, counters, beds, doors, computers and even objects included with the base game or an expansion pack.
Although outdated mods are the most common cause on PC and Mac, the Sims 4 Script Call Failed error can also happen because of damaged game files, broken object data or a problem introduced by a recent game update.
How to Fix the Sims 4 Script Call Failed Error
The quickest way to fix the Sims 4 Script Call Failed error is to temporarily remove your Mods folder, delete the localthumbcache.package file and test the game without any custom content installed.
Close The Sims 4 completely before changing anything inside the game folders.
Open Documents, followed by Electronic Arts and The Sims 4. Find the Mods folder and move it onto your desktop. Do not delete the folder, as this contains your downloaded mods and custom content.
While still inside The Sims 4 folder, find localthumbcache.package and delete it. The game will automatically generate a fresh version the next time it launches.
Open The Sims 4 and test the same object or action that previously caused the error. If the object now works normally, one of the files inside your Mods folder is responsible.
Do not save your main household while testing with mods and custom content removed. Saving without custom content enabled can cause downloaded furniture, clothing and other objects to disappear from the save.
Exit the game without saving once you have completed the test.
Remove Outdated Sims 4 Mods and Custom Content
Outdated mods are one of the most common reasons for the Sims 4 Script Call Failed error, particularly after a major game update.
Game patches can change the scripts, tuning files and object data used by mods. A mod that worked perfectly before an update may stop working afterwards, even if you have not changed anything inside your Mods folder.
Check the websites or download pages belonging to the creators of your installed mods. Look for an updated version that confirms compatibility with the latest Sims 4 patch.
Replace the old version rather than placing the updated files alongside it. Keeping multiple versions of the same mod can create additional conflicts.
Script mods, gameplay overhauls, custom careers, custom traits, food mods and objects with new interactions are particularly likely to require updates after a patch.
However, ordinary custom furniture can also cause the Sims 4 Script Call Failed error. A broken counter, bed, appliance, computer or decorative object may affect other items that use the same game resources.
Use the 50 50 Method to Find the Broken Mod
When the Sims 4 Script Call Failed error disappears after removing the Mods folder, you need to identify the exact file causing it.
The fastest method is commonly known as the 50 50 method.
Split the contents of your Mods folder into two groups. Return one group to the Mods folder, delete localthumbcache.package again and launch the game.
Test the object that caused the error.
If the error returns, the broken file is somewhere inside the group you just added. If the game works normally, the broken file is likely inside the other group.
Continue dividing the affected group into smaller batches and testing each one. Eventually, you should narrow the problem down to a single mod or custom content file.
Delete the broken file or download a properly updated version from its original creator.
Remember to delete localthumbcache.package whenever you remove or replace mods. Otherwise, cached information from the previous files may continue affecting the game.
Repair The Sims 4 Game Files
If removing all mods and custom content does not fix the Sims 4 Script Call Failed error, the next step is to repair the game.
Open the EA app and select Library. Find The Sims 4, open the menu on the game tile and select Repair.
The EA app will check the installed files and replace any that are missing or damaged. Allow the repair to finish before launching the game again.
Players using Steam can verify the integrity of the installed game files through the Properties menu for The Sims 4.
Repairing the game does not normally remove your saves, households or Mods folder. However, creating a backup before troubleshooting is always sensible.
Reset The Sims 4 Folder
A damaged file inside your main Sims 4 folder can sometimes cause the error even when the Mods folder is empty.
Before resetting anything, copy the complete The Sims 4 folder from Documents and paste it onto your desktop as a backup.
Rename the original folder or move it away from the Electronic Arts folder. Launching the game will create a completely new Sims 4 folder with fresh settings and no saves, mods or downloaded content.
Start a new test save and check whether the same object still displays Script Call Failed.
If the object works in the fresh folder, something inside the original Sims 4 folder is causing the problem. You can begin copying your saves and other folders back gradually, testing the game after each addition.
Do not delete your original folder until you have confirmed that your saves and important files are safely backed up.
Sims 4 Script Call Failed on PlayStation or Xbox
Mods and custom content are not available in the console versions of The Sims 4. Therefore, a Sims 4 Script Call Failed error on PlayStation or Xbox is not being caused by an installed mod.
If only one specific object is affected, the problem may be an item-specific game bug. Test a different version of the object, a different colour swatch and another save file.
Close and restart the game, restart the console and make sure that both The Sims 4 and the console system software are fully updated.
You can also remove the affected object, travel away from the lot and return before attempting to place it again.
If the same official object continues to produce Script Call Failed in a new save, the issue may need to be corrected in a future game update.
Why Does Script Call Failed Appear on Base Game Items?
A base game item can display the Sims 4 Script Call Failed error even when the object itself is not broken.
Custom content is often built using an existing Sims 4 object as its base. When the custom version becomes outdated, it may interfere with other objects using related resources.
This is why removing the entire Mods folder is an important test. Deleting only the item that appears broken may not remove the mod that is actually causing the conflict.
If the error remains with a completely empty Mods folder and after repairing the game, test inside a new Sims 4 folder. This helps determine whether the issue is connected to your user files or the game itself.
Can You Keep Playing After Script Call Failed?
You may still be able to continue playing after the Sims 4 Script Call Failed error, but repeatedly ignoring it is not recommended.
A broken mod or custom content file may cause additional problems with objects, menus, interactions or saved games. Removing or updating the responsible file is safer than continuing to use it.
The best order for fixing the error is to remove the Mods folder, delete localthumbcache.package, test without saving, update broken mods, repair the game and then reset the Sims 4 folder only if the earlier steps do not work.
