Hello, a couple of minutes ago my computer crashed while I had my world open in minecraft, after that I restarted my computer. But then, as I started up minecraft and clicked on singleplayer I noticed that my world save wasn't there! I looked if the world save was in /roaming/.minecraft/saves and it was... But somehow minecraft wouldn't open the file.

So I tried copy and paste it again but minecraft still couldn't load the world save... If you've seen what I done in my world save you would be pretty upset too!!! (http://www.planetminecraft.com/project/island-village-156727/)

But then I thought if I restored my computer to yesterday some of my creation would be saved atleast, so that's what I did... When the whole thing was completed I started minecraft again but as before, it wasn't there!

Well, well I thought. Let's begin this thing from the beginning again... 3 days of work!

But for some reason I opened MCedit to do something, dunno what =) And there it was! My world save (1), I was so happy... and relieved! The only thing was that my world save had changed to survival and my player spawn underground... And also that all the biomes were messed up...

So if theres anyone who had a similar problem, use McEdit to restore your minecraft world save!
