My save has been lost, and there is no progress.backup folder. Not sure what im supposed to do but that was a lot of work i had and its just gone. I've seen other players losing their saves too. What the hell is going on??

I was steadly, smoothly playing until couple hours ago, had to restart computer and all my save was lost. Just like that. Hours and hours of work gone

Same here. Hours of work and two of my houses I spent so much time on are back to the beginning. I'm so mad

I tried uninstall/reinstall and nothing.

532 hours played LOST
