Sims and EA just erased progress of my game!!

Oh that really sucks. So many including me have had problems with this broken update. 

When you open the sims save file in your file explorer, there are a whole bunch of documents that start with "slot". Copy those onto your desktop or somewhere else. Just save them just in case cause those are your save files. Check the dates on them, when they were last modified. If these are also showing may 25th that's no good. If it shows July 1st then there's ways to restore it. 

Once you have copies of your saves on your desktop or where you choose, try repairing the game if you haven't already.

Open the ea app and in your library, open the sims tap (don't run the game). Next to the play button, there should be three dots, press that and there should be 3-4 options. Press "Repair" and it'll (hopefully) repair your game. 

Run the game again and see if anything changed. If not, let us know.

(I don't work for ea, I've just had similar problems like this before)

bluetvpaz  Is your Sims 4 user folder (saves, Tray, etc.) stored externally, or do you only keep backups there?  Is the game installed there too?  If so, are these two folders separate or combined?

Additionally, if OneDrive is running on your computer, whether you deliberately use it or not, check onedrive.com for your missing saves.  Look in both My Files and the Recycle Bin.

You can also search This PC for Slot_ , which should turn up any saves that landed elsewhere.
