After the 19 August 2025 patch, my game is literally unplayable.
I am able to load as far as the main menu, and I can choose a save to load, but I cannot load any lots. When attempting to load a re...
Ideas
This new update broke my game; I can't even play my loads with/without mods. plus, why was this update so huge I had to uninstall other games just for a broken update. fix this now EA, this is so frustrating.
Everyone in this thread need to post their LastExceptions in Documents\Electronic Arts\The Sims 4
- Delete the ones you have
- Trigger the error again
- Check if new ones are created
- If that is the case, please copy/paste the content here. You can open the file with any text editor.Deleting the file won't fix your issue. Posting the info is meant for troubleshooting.
Any posts that are on modded game WILL be moved to the mods forum. You need to test a properly vanilla save, moving your mods folder to the desktop, deleting localcachefile thread (or even better a folder rename)
Instructions for folder rename
- Close the game
- Rename Documents\Electronic Arts\The Sims 4 to Documents\Electronic Arts\The Sims 4_Old
- Repair the game
- Start the game. All your content will be gone now as the game created a new folder. All your saves/.. is still in the old folder so not to worry.
- Start a new save game
- Check if you still have the error
- Report back with your results for further steps on how to get your stuff back.
I did the folder rename and it seems to be working fine now, how do i get my old saves back? would i just move them into the new sims 4 folder?
You can now start to copy back things from Documents\Electronic Arts\The Sims 4_Old to the new Documents\Electronic Arts\The Sims 4 folder that was created.
First only copy (I suggest to copy so you can go back in case anything goes wrong along the way) the content of the folder Saves (these are your save games). If you are prompted if want to overwrite a save, decide if you want to keep that testing save you just made or not. If not, just overwrite if, if you want to keep it, rename the save to a different number that isn't taken.
Test just your save game with nothing else added back. If that works, you can start copying back the rest. If not, check back.
You will need the following folders
- Tray (your households and lots you have saved to library)- Custom Music (if you added any)
- Screenshots (if you've taken any)
- Videos (if you've taken any)
- ConfigOverride (if you made any although I recommend redoing those)
- Options(.ini) (although I recommend to just redo your settings in the game)
- usersettings.ini
Now test again. If that still works, you can put back your mods. Put them back in groups and make sure they are still compatible with the game.
All other files are recreated and not needed.
I'm reporting on my experience. I had the same problem. I deleted all mods and CC, cleaned everything (cache), but I still had the same problem. Then I renamed the Sims 4 folder as described here, repaired the game, and restarted the game. The game worked after that. Then I copied my old save folder and tray and everything else into the new Sims 4 folder as described here. Everything works now. After that, I even copied my CC in (but no mods), and there are no problems. So it doesn't seem to be the mods related. The old Sims 4 folder didn't work without mods either. I attach the lastexeption und lastcrash file from my sims4_old folder for you analysis.
Is this a temporary solution to the problem? While it gets fixed? Or will it remain broken? Just as ive tried this and its remained broken, I still cant load my household, just worried for how long this will take to fix
I have the same issue. I repaired the game and deleted all mods.
I still can't load my last save, where I used mods and cc, because I'm stuck in the loading screen. If I start a new game save or load one where I didn't use mods or cc it works.
This is the LastException I get:
