Game won't save since update

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do.
• What platform are you playing on (PC, Mac, Playstation, XBox)

• Do you have any LastException files 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. 

I do have mods, which have been updated to make sure they are the most recent version. I have tried without the mods but the same error appears. I play on my laptop. I know the error message has the name of one of my mods in but the error comes up even when I turn them off. This is it pasted in:

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
  • localthumbcache
  • Any lastException Files
  • Any LastCrash files.
• Test on the backup of your save as you will loose all cc on the save and see if the same error occurs, then report back.

This is what came up this time:

Do you have issues with a particular save only or also on a new one ?

I've just tried a new one which wouldn't let me load the actual house to play and also wouldn't let me save. No new lastexception file was created though this time.

Have you tried renaming the entire user folder as well ? Usually if not even a new save works, that's the best way to go.

Try the following

- 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.
