The latest Sims 4 update left MissLollypopSims with all of her long-running saves corrupted. While frustrating, it became the push she needed to restart her Sims 4 folder and rebuild her CC collection from scratch. Along the way, she shared a complete workflow for keeping mods and custom content organized, updated, and safe.

Here’s a breakdown of the process and tools she recommends.


Structuring your mods folder

  • Organize by creator
    Each creator gets their own folder (e.g., Basemental, Lumpinou). Inside that, mods remain loose. This avoids the “too many subfolders” issue that slows loading times and can break script mods.
  • Special folders for CAS, Build/Buy, and Overrides
    • CAS CC separated into age groups, presets, skins, sliders, etc.
    • Build/Buy sorted by creator.
    • Overrides split into defaults, UI mods, tuning, and world/object overrides.
  • Why this system works
    • Faster loading times than multi-subfolder systems.
    • Easy to remove or update mods when creators release fixes.
    • Keeps conflicts in check when only one override (like CAS backgrounds) can exist at a time.
  • Load order tricks
    Certain mods need to load first. Add symbols (e.g., ! or numbers) to ensure those folders are prioritized.

Visual organization with custom icons

Use Midnight Tech’s folder icons to assign clear visuals to important folders like CAS, Build/Buy, and Overrides. Icons make it easier to spot and manage critical sections of your setup.


Tools to manage and fix CC

Sims 4 Studio

  • Batch-edit CC display indexes so items from the same creator appear together in CAS.
  • Run batch fixes after patches (e.g., broken beds, DirectX11 image issues).
  • Disallow CC for random townie generation.

Google Sheets Mod Tracker (free template)

  • Track mods by name, creator, type, status (updated, broken, etc.), and folder path.
  • Especially useful for overrides and defaults that can’t be duplicated.

Better Exceptions by TwistedMexi

  • Detects broken mods or conflicts when “last exceptions” appear in game.
  • Generates readable reports with possible causes.
  • Can also identify CC used in outfits to track down broken or unwanted items.

Mod Manager

  • View all CAS CC with thumbnails.
  • Delete or deactivate items (like unused hairs or pose accessories) in bulk.
  • Detect duplicate files and remove outdated versions.

Tray Importer

  • Lists all CC used in a build or Sim saved to your library.
  • Lets you track and delete specific Build/Buy items without digging through merged package files.

Clean Launcher (Midnight Tech)

  • Launches Sims 4 with cache cleared and error logs reset.
  • Optionally autosorts mods for beginners, though not recommended if you already use a manual system.

Handling updates

  1. Move all mods into a testing folder after a Sims 4 patch.
  2. Add them back in groups (or individually for large collections) to test stability.
  3. Use Discord servers or Scarlet’s Mod List to check if mods are confirmed updated or broken.
  4. Use Lumpinou’s Milestone Fixes to save households when mods are temporarily removed.

Final tips

  • Always back up your Mods folder before running fixes or testing.
  • Remove default replacements and no-EA eyelash mods before batch-fixing.
  • Keep Better Exceptions installed permanently—it catches problems faster than manual checks.
  • Don’t be afraid to cull duplicate hairs, presets, or accessories. Mod Manager and Tray Importer make cleanup painless.

MissLollypopSims is now starting over with a forever save file, blending custom-built families, renovated lots, and rotational gameplay into a long-term series.

Sims 4 Mods & CC Maintenance – FAQ

What is the safest way to organize my Mods folder?

Sort by creator. Give each creator a single top-level folder and keep their package files loose inside it. Use separate top-level folders for CAS, BuildBuy, and Overrides. This avoids deep folder paths that break script mods and keeps loading fast.

Why do people use an Overrides folder?

Overrides must stay unique and load in a predictable order. Split them into subfolders like CAS defaults, UI mods, tuning, and world or objects so you never install two backgrounds or two mosaics at once by mistake.

How do I control load order for sensitive mods?

Prefix important folders with symbols or numbers so they sort first, for example !_Core or 01_Overrides. Some mods must load before others to work correctly.

How do I make one creator’s CAS items show together in-game?

Use Sims 4 studio. Run Batch Fix – Change CAS Display Index and sort by package name. Do this per creator and assign each a unique index. Now their items will list together in CAS.

What tools should I install first?

  • Better Exceptions – catches conflicts and bad mods
  • Sims 4 Studio – batch fixes, CAS sorting
  • Mod Manager – thumbnails, deactivate or delete CC, find duplicates
  • Tray Importer – find BuildBuy CC used in lots or Sims
  • Clean Launcher by Midnight Tech – clear caches and launch clean
  • Folder icons by Midnight Tech – visual sorting

How do I test after a game update?

Move all mods to a temporary testing folder. Add them back in small groups and launch the game. Use Better Exceptions to catch issues. Check creator discords or Scarlet’s Mod List for update status. Keep broken items out until fixed.

Can I rescue saves if I must remove mods temporarily?

Try Lumpinou’s Milestone Fixes. These scripts can soften missing-mod side effects while you wait for updates. Always back up saves first.

How do I stop broken or unwanted CC on random townies?

In Sims 4 Studio, batch fix to disallow CC for random. For specific problem outfits, use Better Exceptions – Locate Outfit CC on the Sim to see the exact file and remove it.

How do I quickly clean duplicate or outdated CC?

Open Mod Manager – Tools – Find duplicates. Keep the newest file date and delete the older copy. For big CAS sets, use the thumbnails view to bulk delete styles you never use.

How do I track everything without getting overwhelmed?

Use a simple mod tracker sheet. Record mod name, creator, type, link, status, and folder path. Focus on high impact items first – overrides, defaults, script mods, and any pack-wide overhauls.

My game loads slowly. What can help?

Shallow folder depth, fewer subfolders, and creator-based sorting help. Deactivate pose accessories and large sets with Mod Manager when not in use. Use Clean Launcher to clear caches before launching.

What should I back up regularly?

Saves, Tray, and your Mods folder. Before big batch fixes or patch days, zip up Mods and Saves so you can roll back in one click.
