This has been asked before and I will ask again: How do you make the biome CD? I NEVER got it working. I was using the worldedit mod for 1.6.4: Only made a little part of the selected area CD. I used voxelsniper as a plugin on my server (the one for 1.6.4): Kept deleting itself. It doesn't work on worldpainter. I'm desperate here, folks!
