Scott, thanks for your quick response. I have Ultimate Terrain, GE Pro, and the only thing I have for M76 is a modified AFCAD2 that someone on a forum made for me. These buildings were not in my taxiway until maybe a month ago. I have not added any scenery to picayune during this time. I thought they may have been off the airfied somewhere previously. really don't recall. Hope this info is helpful. I have way to much on my flight simulator to even think of uninstalling. I think I would live with the objects first. Whatever you can do would be appreciated.
