Since we don’t screen or support any Mods, we can’t be sure a Mod that didn’t cause any issues for players before won’t cause them after an update.

By disabling Mods when we update, we try to limit any issues or problems with your gameplay. You can check with Mod creators to find out if they’re still compatible after a patch or update.

A Mod may need to be fully reinstalled to be compatible with the latest game patch. Keep in mind that it can take time for Mod creators to upgrade their content after an update.

You can re-enable Mods that were disabled during an update through the Options Menu. Be sure to use caution and understand there may be risks if you re-enable a Mod that hasn’t been updated by its creator yet.

Before re-enabling any Mods after an update, check that your game is working correctly.

1. Launch The Sims 4 with Mods disabled. Choose Resume or Load Game and play in Live Mode to make sure everything is working correctly.
   • When you check if your game is working correctly with Mods disabled, any Custom Content you have installed won’t appear in-game.
2. Close the game without saving by opening the Menu from the top-right in Live Mode and selecting Exit Game. Confirm you want to exit without saving by selecting Exit Game again.
   • If you select Save and Exit before re-enabling Custom Content and Mods, content may be removed from your saved game.
3. Check the Mod creator’s site to verify that the Mod works with the latest The Sims 4 Update. If there’s an updated version of the Mod, follow the Mod creator’s instructions for replacing the outdated version.
4. Re-enable Mods through the Options Menu by choosing Game Options > Other > Enable Custom Content and Mods.
5. Exit the game and relaunch it. Check that the Mod is working correctly. If you need help troubleshooting, use our steps to find out which Mod is causing problems.
6. If there are Mods causing problems, remove them and check the Mod creators’ site for an updated version.
   • As a member of The Sims Community, you can also contact the Mod creator to let them know their Mod is causing issues.
   • Be sure to include your current game version number when you let them know. You’ll find this on the lower left side of the Main Menu.

Mods can cause issues and conflict with The Sims 4 in many different ways. If you’re having problems with your game, there’s no single way to determine if Mods are the cause. The easiest way to see if there’s an issue is to play the game. There may be very obvious problems, such as the game failing to boot or load saves, but other, smaller issues may also mean a Mod is causing problems.

• If you’re using Custom Content, check content like items or clothing to make sure it’s working normally. For example, if your Sim’s hat is floating above them, it’s usually a sign that something’s wrong with that Custom Content item.
• If you’re using Game Mods, make sure everything is functioning like it’s supposed to. While Sims love to ignore us, if they’re walking up walls or have been eating dinner for 24 hours, that may be a clue the Game Mod is causing an issue.

Some error codes that appear in-game are directly related to Mods. Here’s more info about some of the most common Mod-related error codes and what causes them.

102, 123, 125, 127, 129, or 131

This error code usually appears if there’s an issue with the game’s script, so a script Mod could be the cause.

110

This error code usually appears after a game update, and is caused by outdated Mods.

Once you’ve identified that one or more of your Mods are creating issues, you need to figure out which Mods are the problem. If you have a lot of Mods in your Mods folder, this could take time.

Here are some tips to help speed things up:

Remove all your Mods from the “Mods” folder and add them back in batches.

1. After adding each batch, launch the game to see if the problem persists.
2. If you add a batch and the game runs without problems, it’s unlikely the Mods in that batch are causing the problem.
3. If you add another batch and the issue returns, it usually means at least one problematic Mod is in that batch. Be sure to keep track of the Mods you’re adding to each batch.
4. Once you determine that a particular batch contains a problematic Mod, remove half of that batch. Launch the game again to see if the problem still exists.
5. If it does, then remove another half of the batch and try again.
6. If it doesn’t, add back half of the removed Mods and try again.
7. Repeat this process until the problem Mod is identified. This type of searching is sometimes referred to in The Sims community as the 50/50 method.

Remove Game Mods from your Mods folder before Custom Content.

1. Game Mods, which are Mods that add features or change the functionalities of the game, are more likely to cause issues than Custom Content.
2. To narrow down your search, start by just removing only Game Mods Then, launch the game to see if the problem persists.
3. If the problem persists after removing only Game Mods, it might be Custom Content that’s causing issues.
   • If the game works correctly and you don’t experience any issues after removing only Game Mods, one of the removed Game Mods is likely to be the cause.

If you use a lot of Mods, it may lead to performance issues. We don’t limit the amount you can install, but since Mods may require more memory and CPU resources, running them can impact your game.

How to turn off the Show at Startup setting

To speed up how long it takes your game to load, try turning off the Show at Startup option. When this setting is turned on, it lists the Mods you currently have installed, which can slow down the process of opening up your game.

Here’s how to turn this setting off.

1. Launch The Sims 4. Once the game has loaded, you’ll get a pop-up notification listing all Mods you use.
2. Uncheck the box beside Show at Startup in the bottom left of the pop-up notification. When you deselect this option, your Mods list will no longer appear at startup.
