this happened when i teleported to another world!

 

Some have found that if vines have grown into the void and are removed by MCEdit externally, then the world will become stable again. It crashes because the world loads with the vines below the void.

 

oh
BTW that is fixed now

 

@Xx_Pdsterling_xX, you have a corrupted chunk somewhere.
Use this to fix it. http://www.minecraftforum.net/forum...inecraft-tools/1261480-minecraft-region-fixer
