AnvilChunkLoader exception spam

Title: AnvilChunkLoader exception spam

Version: 0.5.1

OS: Windows Server 2012 Standard

Java Version: Java 7 Update 9 64-bit

Description of Problem:

Every time something causes chunks to be saved in my city (At least I think that's the cause. It seems to happen when somebody logs out, or when Essentials saves the world.) I get a massive wall of errors in the console. There doesn't seem to be any actual issues caused ingame, but an error is an error, and it's making my console really hard to read. I get about 20 of these. I don't even think there are any chunkloaders, unless somebody put some down that I didn't see.

Nobody has anything on this?

Try hitting F9 to check if there are actually any chunkloader blocks placed anywhere. I'm not getting this bug with the dimensional anchors I keep in my world, but those are the only type of chunkloader blocks I use.
