The new bukkit unstable builds, has crashed and corrupted the map. The bukkit created a memory dump, and created a entity (player) error. This corrupted the map after the server crashed.
But not all hope is lost!
I have gotten a schematic of the spawn, and the areas around and I positioned it in the same place as before in the same seed (after many hours of mcediting).
Sorry if you have lost your house or items!
I hope there will be a reccomended build soon, in which the server will be much smoother.
Thanks
Harry.
Oh and I will need some people on to help smooth out spawn, looks a bit rough after mcedit
