Zip, did you fix the onBlockRemove to call super.onBlockRemove? I fixed it in one of the bukkit versions I posted a few days ago, but it seems that several people are still having problems with it...
So if I grab yours from the other site it works? I'm using not sure what one haha.
edit: n/m goes to this page
