Hello all. I've been running a 1.0.0 vanilla server since it was released and now I've decided to switch to CraftBukkit. Although, for some odd reason, CraftBukkit disagrees with my current world and gives this error in the console: Does anyone know the solution to fix this? We've done a lot of things to the world and we really don't want to reset it. Thanks. EDIT: I've backed up and deleted the world just to see what would happen, and I get a similar error even when regenerating a new world.
