FYI, When working on more than one aircraft, ensure that you load the aircraft project AND you have the aircraft selected in the WORLD MAP/MAIN MENU. Otherwise when you do a save and resynch and/or restart your eye position will be at the aircraft selected in the WORLD MAP/MAIN MENU and Not in the project aircraft eye point. This also affects which flt files are utilized in the start configuration. For me the start config was for the apron.flt file of the wrong aircraft, so my lights were on, master on etc. when I wanted Cold and Dark.
