User blog:Henzukaya/Terraria and Blackouts

Ok, so I was playing Terraria, on this one world where I have everything; literally everything (Except the Rod of Discord), and a blackout occured. An hour later, the power comes back, only to find that there's an empty space where that world should be. The world files are still in my computer, I just can't access the world from Terraria.

Any ideas on what to do?
