the map still works (without the commands as people have previously stated)
I love it. I actually pasted 2 more almost in a square. (maybe ill add 1 more)
changed one of them to be full of water/coral reef/fish (filled with water) for my "ocean dome"
the 3rd is Stone=stone, the dirt to sandstone and the grass blocks to sand, I left the water, I also added a lava pit around the size of the water in my "desert dome"
