    Hi, I am trying to save a 11 by 11 by 11 area of the world to a 3d array, but have a lot of areas. I want it so that when you place a piece of bedrock that it saves the area array it. The bedrock is the center, bottom block of the region.

    Includes extra code for deleting the region, creating a custom block that when place creates the saved region in the world.

    Console Error Code (open)

    Code:
    E:\eclipse\Test Server>java -Xmx1024M -jar bukkit.jar -o true
