I'm sorry, I should have stated "missing vehicles", not parts, which is still a problem.
I am a bit confused. The only option I have with choosing a gate with GSX is after I land at an airport. If I try and do that at the departure gate I pre-select at an airport in FSX and then check GSX for a gate, I only get a menu of "Hangers" , "Hanger door" in GSX. Sometimes upon arrival at an airport, I sometimes will ignore a gate assignment by FSX ATC and go to another gate and/or at another terminal, and it works fine and GSX works plus all the GSX vehicles show up upon request. But of course this was only before the recent download updates I installed. If I do a Ctrl F12 "In flight", can I choose a gate at the arrival airport with GSX? If so, I never tried that before. I always use FSX ATC for gate assignments, and never had any GSX missing vehicles with that, until I downloaded the recent GSX updates. Others may have issues with using FSX ATC for gate assignments, but I never did and GSX worked fine. And if I did not like the gate assignment, I went to another without any problems.
Just a thought. I still have my old GSX downloads from the past year. To end these new problems which I did not have before with GSX, Am I able to re-download an older GSX versions instead? Because I did not have any missing vehicles at all back then.
