Lost All Game Progress Sims 4

Thankyou so much for your response, i have just downloaded origin, clicked on the advanced launch options and there isnt any drop down list reguarding the 32 or 64bit, i dont know if im doing something wrong?

UPDATE

I've redownloaded origin and had to update the game to change it to a 64bit instead of 32bit legacy addition. I then logged back into my OneDrive and launch the game after waiting a few mins.

When I launched it, my saved game was back!! BUT from a month ago, its better than nothing!

@elliemisson  That's good to hear.  If you want to look for newer saves, try searching your computer.  Open a File Explorer window, click This PC in the left panel, and enter Slot_ in the search field in the upper-right corner.  This should turn up any saves stored internally (as opposed to in OneDrive).  If you find some, you can move them to Documents > Electronic Arts > The Sims 4 > saves, and they should show up provided they're in the correct format.

As an aside, I'd suggest disabling OneDrive again, or at least not allowing it to sync the contents of Documents.  If your internal drive gets full, OneDrive may store your Sims 4 data only in the cloud, where the game can't find it.  This purportedly space-saving measure has made a number of players' saves disappear over the years.

Before you change any OneDrive settings, make a backup copy of the Sims 4 user folder and store it somewhere else, ideally on an external drive or USB stick, but even the Downloads folder would work in a pinch since OneDrive doesn't sync it.  Then you can restore this folder if OneDrive removes the original from your computer, as sometimes happens when it's told to stop syncing.
