Ah, yes. I got this when I switched my PC off without stopping the server, corrupting the world. Make a new world, point the server at it, and copy the old region and data folders over, but use the new level.dat.
The spawn point will change, but it should otherwise be fine.

 

This is most likely a Chunk error on your World. You can fix It by running a Utility called 'Chunkster'
http://forums.bukkit.org/threads/admin-chunkster.8186/

To run It, this is how:

Code:

java -jar Chunkster.jar [Worldname] [WorldLocation]

*Open up Command Prompt (Windows). If your on a Mac or Linux OS, open Terminal and try to do the same.

Make sure you put the Chunkster.jar in the main root of your Server folder.

 

i did the first one and i have a mac so i cant but files in it and change it back to .jar
