I created a new topic because I couldn't find any solutions yet.

Yesterday I was playing with my friends I'm the host of the game, and everything was perfectly fine, but when I tried to log in today, all my saves were lost. Yes even the auto-saves. The attached image is what shows and then I decided to start again but the same happened to the new save. Is there a way to fix this?

I play on my PC with Xbox game pass.

Just a heads-up, I sent an email to support on the weekend and I received a reply today - stating they believe they've got a fix for it and it should in the patch coming Wednesday. They also said some users have reported that uninstalling then reinstalling the game fixes it, because it forces a sync request to the servers. I'll probably just wait for the patch though haha.
