The disappearing bogeys, I can not explain, for me they started disappearing after I was upgraded to 38599. I have been searching for a fix but have not found reference to this yet.
As for the refueling, there is another post about this - you have to start the engine first. There is a start engine command by clicking on the (i'm colour blind) green arrow beside the driver icon. Once the engine is started, you can proceed to the fuel station and use the load command from the same menu.
Have Fun,
