A warning to everyone wanting to use this mod to convert their desserts into green plains. Each tile that you replace will have some info in your level.dat file in your safe files. I replaced 8x8 chuncks = 256x256 tiles = 65536 tiles with grass and my save game has become very slow.
I'm not sure if there is a way around this but keep this in mind not to use it for terraforming ;)
