The latest public release, MCCC/MC Woohoo 2026.3.0, is out!

Please note that there's a big update coming Tuesday for the Sims 4 and it will likely break a lot of mods. If you are concerned about your content being broken, you should disable automatic updates for the Sims 4 until your mods get cleared for the update!

Full change log for 2026.3.0 is here.

Installation instructions can be found here.

Troubleshooting can be found here.

For support or possible bugs, you should always go to the Discord support channels. We don't do support through PM's:

General Support - Support for other mods or just general Q&A. General Support (Sims After Dark) - Alternate support for other mods or general Q&A Error Support- Last Exception and MCCC questions

Compatibility:

This has been tested to be working with (but does not require) all expansions and game packs up to Royalty & Legacy and the patch released April 28, 2026 - PC: 1.123.85.1020 / Mac: 1.123.85.1220. It will also work with anything after that Sims 4 update unless otherwise specified on Tumblr/Patreon posts I make after the update. Earlier Sims 4 versions may not be compatible, so we often do not support anything below the specified version here!

The legacy version of Sims 4 will now, and forever, use MCCC version 6.6.0, which can be found on Patreon and on my website.

DOWNLOAD HERE:

MC Command Center - All Modules Version 2026.3.0

MC Woohoo - Version 2026.3.0  (optional if MC Woohoo features are wanted)

NOTE: If you get an unconfirmed file in your download folder after trying to download MCCC, you should read the Q&A on my FAQ about that here. It's a browser problem, not a file problem so nothing that I can do to fix it.

The Biggest Sims Creator Just Teamed Up with Congress Against EA

Lilsimsie is teaming up with her Congressional rep - details in the video!

God bless her.

It may not change anything, but CERTAINLY won't if we don't fight.

Spread the word!!! THIS is what us creators should be supporting!

If you've been on YouTube lately, you've probably seen the wave of players dealing with corrupted saves, forever loading screens, and worlds breaking beyond repair. It’s frustrating, but after months of rebuilding my own save (with over 30,000 mods and CC files—yes, really😕), I’ve found some ways to keep major errors at bay.😁

While no save is completely error-proof, these tips might help you avoid game-breaking issues and keep your Sims’ world running smoother.

1️⃣ Backup, Backup, Backup!

Always keep a copy of your save outside the game—on your desktop or an external drive. Do NOT rely on the in-game "Recover Save" feature, because if your save is corrupted, chances are the recovered version is too.

2️⃣ Use "Save As" Instead of Spamming Save

Instead of constantly clicking "Save," use "Save As" and create a fresh save. Overwriting the same file multiple times (7-10 times or more) can bloat the file and slow down your game. Once you've saved a new version, delete the old one (since you have a backup anyway!). This keeps your save cleaner and prevents sluggish performance.

3️⃣ Be Mindful of Lot Placement

Some worlds are known for stuck items, exclamation mark errors, or disappearing lots—especially San Myshuno, Oasis Springs, Willow Creek, and Evergreen Harbor. If you're having issues, avoid placing residential-Rental lots there.

However, I’ve found Del Sol Valley, Ciudad Enamorada, Tomarang, and Ravenwood to be much more stable for residential and rental lots!

4️⃣ Don’t Go Overboard with Mansions

Large homes with tons of clutter and objects can bog down your game. If you don’t love playing super-rich Sims in mansions, consider using large lot spaces (50x40 and up) for community lots instead of oversized residential builds. It helps keep your save lean and functional.

5️⃣ Stop Hoarding Photos

Sims’ in-game photographs and screenshots take up a surprising amount of space. Keep only 10-20 photos per household and delete the rest. Also, regularly empty the "Screenshots" folder in your Sims 4 directory to avoid unnecessary bloating.

6️⃣ Keep Your World Clean

While your Sims sleep, take a quick scan of the neighborhood and delete random objects left lying around (plates, trash, random items). This helps prevent save file bloat and keeps the world from lagging.

7️⃣ Purge Unnecessary NPCs

Check Manage Households and delete unneeded NPCs. The game constantly generates new townies, and over time, they clog up your save. You don’t have to delete all of them, but clearing out a chunk can help performance.

Bottom Line

When your save file becomes bloated with unnecessary things, it becomes unstable! That means it will start to break down and cause issues—just like the errors many players are experiencing right now.

Keeping your save clean and optimized is the best way to prevent crashes, long load times, and corruption before they happen.

Final Thoughts

😕Is my game completely error-free? Nope. Right now, I’m dealing with rain and snow falling inside my Sims’ apartments and houses (because of course, EA). And I still get the occasional MCCC Last Exception (but they’re minor).

However, I’m NOT experiencing the major game-breaking errors that are all over YouTube. A few months ago, my save was nearly unplayable, but these changes made a huge difference.

I hope this helps! If you have any other tips that have worked for you, feel free to share.

PLEASE put your name in your filename. One, someone will have a clue who it's by when they go to find more by you or to finally organize their Mods folder. Two, you're less likely to end up with the exact same filename as another creator.

PLEASE put your name FIRST in your filename. Alphabetization is super useful. It's less useful to alphabetize by the cute name you gave that hair or set of chairs.

PLEASE, for the love of all things Sims, consider not only using your initials. My Mods folder now has three different creators whose files start "MM". There might be even more of you MM's out there.

You are all so awesome and beautiful and good and you post such good pretty nice things for me to look at and wonder about and enjoy, and you are of infinite worth and infinite beauty and infinite goodness, and it is right and correct for you to exist here with all the rest of us right now.
