What is Better Exceptions Mod?

Better Exceptions is a sophisticated script modification that fundamentally transforms how The Sims 4 handles and reports errors. Created by the renowned modder TwistedMexi, this tool acts as an advanced diagnostic system that monitors your game in real-time, catching issues as they occur and translating technical error logs into human-readable reports.

The Three Pillars of Error Detection

Better Exceptions monitors three critical categories of game errors, each serving a unique purpose in maintaining your game's stability:

  1. General Game Exceptions These are the most common errors that occur during regular gameplay. When a mod conflicts with game code or becomes outdated after a patch, Better Exceptions catches these exceptions instantly. Instead of letting errors accumulate and eventually crash your game, the mod alerts you immediately with detailed information about which specific file is causing problems.
  2. UI (User Interface) Exceptions UI errors are particularly insidious because they can break your game's interface without causing an immediate crash. You might notice buttons not working, menus freezing, or panels displaying incorrectly. Better Exceptions tracks these UI-specific errors separately, making it easy to identify which UI mods need updating after game patches.
  3. CAS Custom Content Glitches For CC enthusiasts, this feature is absolutely invaluable. Have you ever had a Sim with missing body parts, distorted textures, or clothing that turns into question marks? Better Exceptions includes a specialized CC tracker that identifies exactly which custom content files are causing visual glitches in Create-a-Sim.

Core Features That Set Better Exceptions Apart

  • Real-Time Exception Monitoring: Unlike the vanilla game that silently logs errors, Better Exceptions actively monitors for issues and notifies you the moment something goes wrong. This proactive approach prevents small problems from snowballing into game-breaking crashes.
  • Patch Day Scanner: Every Sims 4 update brings excitement—and dread. The Patch Day Scanner is your first line of defense after game updates. With a single click, it scans your entire mod collection and identifies which files are incompatible with the new game version. No more testing mods one by one!
  • Browser-Based Detailed Reports: When an error occurs, Better Exceptions generates comprehensive reports in your web browser. These reports include confidence ratings (90-100% accuracy for most issues), specific file paths, recommended actions, and even links to community resources for additional help.
  • Outfit CC Tracker: This ingenious feature lets you shift-click on any Sim with visual glitches and instantly see a list of ALL custom content used in their current outfit. It's like having X-ray vision for your CC collection.
  • Auto-Update Functionality: Better Exceptions can check for updates to itself, ensuring you always have the latest error detection capabilities without manually checking for new versions.
  • Known Mod Error Database: The mod maintains a database of common mod errors, allowing it to provide specific solutions for known issues rather than generic troubleshooting advice.

System Requirements and Compatibility

Before diving into installation, let's ensure your setup meets all requirements for optimal performance:

Minimum Requirements

  • The Sims 4 Base Game (any version except Legacy Edition)
  • Operating System: Windows 7/8/10/11 or macOS 10.7+
  • Script Mods Enabled in game settings
  • Web Browser for viewing detailed reports (Chrome, Firefox, Safari, or Edge)
  • At least 10MB free space in Mods folder

Game Version Compatibility

As of July 2025, Better Exceptions v3.14 is fully compatible with:

  • The latest Sims 4 base game patch (1.116.202)
  • All expansion packs including "For Rent"
  • All game packs and stuff packs
  • The "Enchanted by Nature" expansion

Compatibility with Other Essential Mods

Better Exceptions works seamlessly with other popular mods, actually enhancing their functionality:

  • MC Command Center (MCCC): Better Exceptions and MCCC complement each other perfectly. While MCCC notifies you when lastException files are generated, Better Exceptions tells you exactly what's causing them. Use both for maximum game stability.
  • UI Cheats Extension: No conflicts exist between these mods. In fact, if UI Cheats causes any issues after an update, Better Exceptions will identify the problem immediately.
  • XML Injector: Better Exceptions includes special handling for XML Injector to avoid false positives. Mods using XML Injector are properly recognized and won't be incorrectly flagged.
  • TwistedMexi's Other Mods: All of TwistedMexi's mods (AllCheats, Better BuildBuy, T.O.O.L.) are designed to work together harmoniously with Better Exceptions.

  • Excludes injector module from conflict scans
  • Properly attributes errors to dependent mods

For Mod Creators:

  • Supports both Scumbumbo's original and current versions
  • Accurately traces errors through injection layers

Advanced Configuration and Power User Tips

Customizing Better Exceptions Behavior

FAQs About Better Exceptions

Q: Does Better Exceptions slow down my game? 

A: The impact is minimal. Initial scans may cause brief slowdowns, but during regular gameplay, it runs silently in the background using negligible resources.

Q: Can Better Exceptions automatically fix or remove broken mods? 

A: No, and this is by design. Better Exceptions identifies issues but leaves file management to you, preventing accidental deletion of important files.

Q: Is it safe to use with all expansion packs? 

A: Absolutely! Better Exceptions is tested with all expansions, game packs, stuff packs, and kits. It actually helps identify pack-specific mod conflicts.

Q: Why do I sometimes get errors about Better Exceptions itself? 

A: This is usually due to version mismatches. Always update Better Exceptions first after game patches, as it needs to match your game version.

Q: What's the difference between Game and UI exceptions? 

A: Game exceptions affect gameplay mechanics (interactions, behaviors, systems), while UI exceptions specifically impact interface elements (menus, panels, buttons).

Q: How accurate is the confidence rating? 

A: Ratings above 90% are extremely reliable. The mod correctly identifies the culprit in approximately 95% of high-confidence cases.

Q: Can I use Better Exceptions with the Legacy Edition? 

A: Unfortunately, no. The Legacy Edition lacks support for script mods entirely, making Better Exceptions incompatible.

Q: Do I need to update after every game patch? 

A: Usually yes. TwistedMexi typically releases updates within 24-48 hours of game patches to maintain compatibility.

Q: My browser won't open the reports. What should I do? 

A: Reports are saved as HTML files in your Sims 4 folder. Navigate there manually and open with any browser. Check security settings if issues persist.

Q: Better Exceptions says a mod is broken, but it seems to work fine? 

A: Some errors don't cause immediate visible issues. The mod might work now but cause problems later. Consider updating or monitoring closely.

Q: Can I disable certain types of scanning? 

A: The mod scans comprehensively by design, but you can ignore specific error types through the notification system.

Q: How does this compare to Mod Conflict Detector? 

A: They serve different purposes. Mod Conflict Detector finds resource conflicts between mods, while Better Exceptions identifies runtime errors and crashes. Use both for complete coverage.

Q: Is this better than MCCC's error logging? 

A: They complement each other. MCCC logs that errors occurred; Better Exceptions tells you exactly what caused them and how to fix them.
