After the Alien BIomes update I can't plant trees on any Lignumis Grass, I can still "plant" gold but trees are done. Tested already, if I disable Alien Biomes everyhting works fine, not sure who to contact about it I'm coming to u first. I'll go to the Alien Biomes forum if u say it's something only the AB Author can fix
