I have a survival world with my friends that I've been playing on for 2 - 3 weeks. All of the sudden when I tried to connect to the world, it said that the world was corrupted and to contact bugs.mojang.com.

I have a survival world that said that it was corrupt. I would like to get this world back because I truly enjoy playing on it. The message telling me that the world was corrupt was sudden, and there is no reason identifiable for the world to become corrupt.
