[SOLVED - world corrupted] java.lang.Exception: Stack trace

I've recently imported from hMod to Bukkit and I'm getting lots of erros, which I already had but thought that Bukkit would figure it out. Here's some of the logs, it's 50mb so I won't post it all:

Code:

This error makes mobs not spawn and gives world generation bugs, like buildings replicated in nowhere or lakes where roads stood

 

maybe corrupted world, try Chunkster

 

YES! Finally the World is fixed, thanks for the help. Although I regenerated the world using the same seed again it's good to know that those errors can be repaired
