Loaded it a used mission that i have used many times at Nellis and for some reason no the ground crew refuel/rearm, ground power do not work. I have easy coms and coms assist on in the settings menu. I can get to the ground crew part of the atc menu but when i click on refuel/rearm nothing happens and it is also stuck in the ground crew menu I cannot even back out to the main communications menu any more.
