Hi, so last night I finished playing and logged off. This morning I went to hop back on and continue my exploration. Well when I went to load my game the save was gone. It still has a world my friend shared with me and a save from early access but my current one is gone. I had an immense amount of time into this save and was at the last mission for the story, so this really really is a drag. Any help would be amazing.
