Few things are as frustrating for a dedicated player as attempting to save your game only to be interrupted by a persistent notification. If you are struggling with the dreaded Error Code 102 in The Sims 4, you are not alone. This error typically occurs when the game fails to save your progress, often due to corrupted files, outdated mods, or issues with the game cache. Fortunately, learning how to fix Sims 4 error code 102 step by step is relatively straightforward, and most players can resolve it without losing their progress.
Error Code 102 is fundamentally a save-game error.
It signals that the game engine encountered a conflict while writing your save data to the hard drive.
While it can be alarming, it rarely indicates that your entire game installation is broken.
Instead, it is usually a localized issue involving specific files or a conflict between the game software and your operating system.
By following a systematic approach, you can identify the culprit and restore your gameplay experience to normal.
Understanding Why Error Code 102 Occurs
Before jumping into the fixes, it is helpful to understand why this happens.
In most cases, the culprit is outdated Custom Content (CC) or game mods that have not been updated to match the latest Sims 4 patch.
When the game updates, these mods can conflict with the new code, causing errors during the saving process.
Other causes include corrupted game files resulting from an incomplete update or a cluttered cache folder that stores temporary game data.
How to Fix Sims 4 Error Code 102 Step by Step
If you are ready to get back to building your dream home, follow these proven troubleshooting steps in order.
We recommend trying them one by one to isolate the issue.
Step 1: Remove or Update Custom Content and Mods
The most common cause of Error Code 102 is incompatible mods.
To test this, navigate to your Electronic Arts folder, find the 'Mods' folder, and move it to your desktop.
Once moved, launch the game and try to save your progress.
If the error disappears, one of your mods is the cause.
You can then use the '50/50' method—putting half your mods back in at a time—to identify exactly which file is corrupt.
Step 2: Repair Your Game via the EA App or Steam
If removing mods does not resolve the issue, the game files themselves might be corrupted.
Fortunately, you don't need to reinstall the entire game.
If you use the EA App, go to your 'Library,' click on the three dots on The Sims 4 game icon, and select 'Repair.' If you are playing through Steam, right-click The Sims 4 in your library, go to 'Properties,' select 'Installed Files,' and click 'Verify integrity of game files.' This process checks for missing or broken files and automatically replaces them.
Step 3: Clear Your Cache Files
Temporary cache files can become corrupted over time, leading to strange behavior in the game. To clear the cache, close the game completely. Go to your 'Documents/Electronic Arts/The Sims 4' folder and locate the file named localthumbcache.package. Delete this file. It is perfectly safe to delete because the game will automatically regenerate a fresh, clean version the next time you launch it.
Step 4: Use the 'Save As' Workaround
Sometimes, the specific save slot you are using has become corrupted.
Instead of clicking the 'Save' button, go to the menu and select 'Save As.' Create an entirely new save slot with a different name.
This forces the game to write a fresh save file rather than attempting to overwrite a potentially corrupted existing one.
This simple trick often bypasses the 102 error entirely and allows you to keep playing without losing your current household.
When to Contact EA Support
If you have tried all the steps above and are still seeing Error Code 102, the issue might be deeper, perhaps related to Windows permissions or conflicting background software like antivirus programs.
In these rare instances, it is best to visit the official EA Help website.
Reach out to their support team, and be sure to provide them with your specific platform details and a list of the troubleshooting steps you have already completed to speed up the process.
Frequently Asked Questions (FAQ)
Will I lose my save file if I get Error Code 102?
Not necessarily.
In most cases, using the 'Save As' function to create a new file allows you to continue playing from your current point without data loss.
Is it safe to delete the localthumbcache.package file?
Yes, it is completely safe.
This file only contains temporary cache data, and The Sims 4 will generate a fresh, clean copy automatically the next time you start the game.

No, a full reinstall is usually unnecessary.
Using the 'Repair' function in the EA App or Steam is almost always enough to fix corrupted game files.
