When I logged in today, I noticed that my bookmarks are gone, and I was really confused, but then I realized that not only were they gone, but so was my universe with my home planet in it, where most of my valuable and important items remained. In my universe folder I have a lot of world files with the same coordinates, and two .FAIL files. I'll provide a screenshot with this post. Is there any way to revert this removal, and would someone please help or inform me about this?
