Okay, so once again they've updated Minecraft. The newest version is 1.3.1 and we have the server running 1.2.5. Again, it looks like the bukkit developers are behind in coming up with a craftbukkit 1.3.1, so we have to wait until they finish before I can update the server.
Basically, once they come out with a Beta build or Recommended build of 1.3.1: http://dl.bukkit.org/downloads/craftbukkit/
