This is WorldModify. Thank you though, I was able to load the world in MCGalaxy, use the command, then move the world back to singleplayer.

I accidentally flooded a world with lava. I tried using WorldModify to fix it, but looks like its Fill feature would only work if I had a way to select the Air / empty block. Is there an equivalent to a /give command, or some other way to remove all of a single block type from a world?
