Hello, I have a Bukkit (1.5.2-R0.1 Beta) server, which constantly crashes because of an NBT problem. I use Multiverse to manage worlds, and this world is a (vanilla) superflat world. Here is the crash report. http://pastebin.com/YLkKPiSp This looks like one faulty NBT tag, but I'm not sure what to do about it... I can't pinpoint exactly where it is feasibly, so I can't get in game and do anything. So is there any way I can either fix or regenerate this chunk? (if this is such a problem) EDIT: VoidChunk fixed this for me. Testing the fixed chunks on my server... EDIT 2: It seems to have worked!
