When I land at an airport, shutdown and go to the radio menu to refuel, so "Ground Crew > Rearm and Refuel" I put my fuel back up to a 100%, but the pilot only says "request rearming" and Grnd crew responds with "copy". and after a few seconds the rearming is complete. But refueling never starts when I'm shutdown, also doesnt start when everything's running. I think its a bug.
EDIT: I found out i was at an airport without fuel providers. :pilotfly:
