[NEEDS SAVES] Save Error code: 422:3f003cc3

I tried this, it did not come up with the error code and saved how it should normally but when I loaded back into the game, it didn't save even tho yanno it said it did ☹️ I’m having same issue with error code and not saving 

I restored the file. It’s back in my save folder with the same icon.

how do I check if it’s associated with a program? Yes I moved it back to the Sims 4 save folder 

I'm getting the same error code. My game won't load save files correctly. I went to play again yesterday and none of my progress the night before was saved. The newer dated save files are in my save folder, but it will only load my game from this one particular old save and none of my progress after that save is getting saved correctly making my game unplayable. I have cleared all my cache, taken out all mods and cc, and even started on a newly generated Sims 4 folder, clean start entirely and nothing has worked. 

When I save and exit it looks like it is saving properly but it isn't, and when I try to "save as" I get this error message:

After completely deleting my game and installing it back again it somehow works for now. We'll see if it'll break or not.

Ok so basically, I had the exact same error code pop up after almost 6 hours of playing... I updated the mods I had which were MC Command Center and UI Cheats. Also, I went to the EA App and repaired the game. I've been playing normally since then without any problems. If you have the mods just re-download them and replace the old ones and if that doesn't work, just repair the game on EA. I don't really know what caused the issue but to save some time just do these 3 things and try saving on a new save file. Hope I helped!
