Greetings, finally went to do my first shadowcast map, and I am stuck after several hours. Only interested in some areas shadowcasting, others regular FoW. Spent hours playing and fixing, and when done, room labelled lower48 is now disappeared. Cant bring it up, cant highlight it, can't do anything with it to bring it back. no matter what i do.......Attached map, can someone help? Let me know what I did wrong and or how to fix?
