Comment by Dawson_R2

Same Here I Think its Something with the new 1.4.6 Dev Build (I Guess its very Buggy)

Comment by MrNintendoguy1

I have been reciving the same error. I agree with Dawson R, I think it is something with the CraftBukkit build or the WorldEdit build. If anyone manages to gather any more information, please notify me as soon as possible! Thank you.
