Sims 4: How to Use Better Exceptions

To use Better Exceptions in The Sims 4, put TwistedMexi’s .ts4script file directly in your Mods folder, tick Script Mods Allowed in Game Options > Other, restart the game and keep playing: it reports game and UI errors by itself the moment they happen, and in most cases it names the mod file responsible. For a conflict scan, open its menu from the welcome notification that appears the first time you load a household each session. For a glitched outfit, turn on testingcheats, Shift-click the Sim and choose Locate Outfit CC.

Below we cover what it tracks, where to get the official file, the install, each kind of report, and what to do once a report names a mod. Better Exceptions is a script mod, so this is PC and Mac only: per EA, mods cannot be installed on PlayStation or Xbox.

Better Exceptions at a Glance

What Better Exceptions Does

The game already writes errors to a text file called LastException, which our guide to finding broken CC explains how to read. Better Exceptions does the reading for you. Its CurseForge page says it takes three types of error and adds automatic tracking that can identify the responsible mod file in most cases:

• Exceptions. Errors in the game’s gameplay code, reported automatically when they occur.
• UI Exceptions. Errors in the game’s interface, also reported automatically.
• CAS CC Glitches. Problems with the custom content on a Sim’s outfit, which you look up yourself with the outfit tracker.

TwistedMexi’s site also lists conflicting mods among the things it reports. What it does not do is repair anything. It tells you where the problem is, and the fix is yours to make.

Where to Download It

TwistedMexi’s site links the current download, a free Patreon post, and marked the mod as Updated when we checked on November 8, 2026. There are two official places to get it:

• The Patreon post. It carries v3.17, from June 18, 2026, which improves script mod tracking.
• The CurseForge page. It is free. It had v3.16, from February 23, 2026, when we checked on November 8, and it installs through the CurseForge app.

Start from TwistedMexi’s own site rather than a web search, so you do not land on an old copy. A search can also turn up a locked post marked RC, such as v3.17 RC1 from May 20: that is an early test build for members, and you do not need it.

How to Install Better Exceptions

1. Download the file. TwistedMexi’s install note reads “Download ts4script file directly to Mods folder.”
2. Get the .ts4script out of any zip. Recent releases ship inside one, and the file you want is the one ending in .ts4script (tmex-BetterExceptions.ts4script in recent versions). On a Mac it may come out of the zip on its own when it downloads.
3. Put it directly in your Mods folder. That is Documents > Electronic Arts > The Sims 4 > Mods on Windows and Mac. Our guide to installing mods and custom content covers the folder if you have not used it before.
4. Tick both options. In Game Options > Other, tick Enable Custom Content and Mods and Script Mods Allowed, then apply the change.
5. Restart and load a household. The welcome notification should appear the first time you load a household each session. That is your sign the mod is running.

How to Read Each Kind of Report

Game and UI errors

You do not have to do anything to start these. The CurseForge page says game and UI exceptions are “automatically reported in real-time when the exception occurs,” so a report turns up as you play. Read it for the mod file it names, then go to “What to Do With a Report” below.

The conflict scan

To run a conflict scan, open the Better Exceptions menu from its welcome notification. Do this after you add a batch of new mods or CC, while the changes are fresh and you know what went in.

Glitched outfits in Create a Sim

When a Sim’s outfit looks wrong, the outfit tracker lists what the Sim is wearing:

1. Open the cheat console with Ctrl+Shift+C and type testingcheats true. Our Sims 4 cheats guide covers how testing mode works.
2. Shift-click the glitched Sim.
3. Choose Locate Outfit CC.

The report shows every CC file in use on the Sim’s current outfit, which the page says makes it “easy to update or remove them.”

What to Do With a Report

1. Note the file name. That is the mod or CC to deal with first.
2. Check that creator’s page for an update. Out-of-date files are the usual cause, and that goes for hair and clothing as well as script mods.
3. Replace or remove it. Delete the old file before adding a new one. If a creator has stopped updating a mod, removal may be the only fix.
4. Update any library it depends on. A stale core file, such as XML Injector, can make every mod that needs it look broken.
5. Delete localthumbcache.package and test again. Our guide to clearing the cache shows where it is.

If Better Exceptions cannot find the responsible mod, which its page calls “fairly rare,” the report’s Help and Resources section points you to TwistedMexi’s Discord, where the page says bots and team members “can usually locate the cause.” You can also fall back on EA’s 50/50 method, which our broken CC guide walks through round by round. While you test, exit without saving, because EA warns that saving with mods off can remove that content from your save.

Keeping It Updated After Patches

EA turns mods off with every game update, so re-tick both options after each patch. Then check TwistedMexi’s site for the mod’s status and replace the .ts4script if a new one is posted, keeping only one copy. As of November 8, 2026, the newest game patch is 1.129, released October 27, per EA’s update notes. Our guide to fixing mods after a game update has the full routine, and Better Exceptions is most useful right after you finish it.

When Better Exceptions Does Not Appear

If the welcome notification never shows up, check these in order:

• Script Mods Allowed is off. This is the likeliest cause right after a patch.
• The file is still in a zip. The game cannot read a zip, so extract the .ts4script.
• The file is in a subfolder. TwistedMexi’s note says to put it directly in Mods, so move it up.
• You have two copies. Search your Mods folder for older versions and keep one.
