Yep. Never happened to me before though. Well, Feral heart ALWAYS crashes when I try to mess with Heightmaps and Terrain masks, I think because my only art program is paint, but I just gotta live with it and use the complete flat unnatural ground for everything I make. GRR!! Very funny you had duplicate SKIES though. How is that even possible? Two skies at once? Feral Heart, you can be very annoying, exasperating,maddening and hilarious at times.
