Getting the below error. Any help fixing it would be appreciated;
I have tried to fix this myself by deleting The End, The Nether, and Twilight Forest (hadn't even been in them yet anyways) and I have tried to save the world using MCEdit (as some people have suggested this error means a severe chunk error). Nothing has gotten rid of this error. The error does not prevent me from playing, but I don't like seeing this red error message.
