I'm an absolute newbie in scenery development. I use WED to add taxi ways and aprons and OverlayEditor to put my objects in the airport. It works fine, I save the file, export to custom scenery and test it in X-plane. Everything works, except… when I quit all my programs, and restart my Mac, the objects disappear from the scenery in OverlayEditor and nothing shows in X-plane. My taxi ways and apron are still there but all the objects I had added in OE have gone. Why? did I miss something?
