How to fix ‘script call failed’ error in Sims 4

There’s nothing worse than when you’re enjoying your Sims 4 game only to stumble upon an error. It can ruin your whole flow, whether you’re making a new family, decorating, or building a house. 

One particular error, the Script Call Failed bug, can upset the entire house-building process. You’ll want it solved before the new expansion, Life and Death, comes out. If you need help fixing this error in your Sims 4 game, we’re here to help.

How to solve Script Call Failed error in The Sims 4

The most likely culprit for this error is outdated mods or custom content. You’ll want to remove all your mods and custom content from the game, clear local cache files, and then reload your save to see if this solves the issue.

To do that, head into your Documents folder and find Electronic Arts, then The Sims 4 files. You’ll be able to find your Mods folder here, where all your mods are. Simply click and drag this file anywhere you want.

Next, you’ll want to delete the localthumbnail.package file from that same The Sims 4 folder. This should clear the cache for you.

Reload your game without the mods, and you should no longer get this error when you’re placing furniture or Build Mode items. You’ll be able to place them freely without issue.

If this doesn’t work, make sure to repair the game files, too. In the EA app, right-click on The Sims 4 and choose Repair.

How to find broken custom content and mods in The Sims 4

The most likely culprit for the Script Call Failed error is UI mods. Things like Basemental, MC Command Center, and mods like that cause the most bugs. Make sure they’re updated to the latest versions and that the latest version is up to date with the latest patch.

You can use TwistedMexi’s Better Exceptions mod, which will run in-game to locate broken or outdated files for you. 

For a more in-depth search, open your mods folder and take half the mods out. You can place them in another folder to save for later. Run the game, and if the error persists, it’s one of the mods still left. Continue taking out half of the mods and reloading the game until you’ve found the problem. This method, unfortunately, takes a while, but it is a surefire way of finding the issue.

Once you’ve found the problem mod, you can simply remove it and put your mods folder back into your game. This will let you keep all your custom content and mods while still fixing the Script Call Failed bug.
