If you'd like to recommend a path for Alien Biomes to decay... I see a lot of different color variations of dirt and sand and they could decay within that variation. Snow might look for the nearest color of dirt and decay into that. There's a lot more end-points to consider!
I also agree, even just a simple override to use default AB dirt would be great. It currently breaks if the "disable obsolete tiles" option is checked in alien biomes. Would love to free up some tile IDs and still use this mod.
