Hi, recently I have a problem with GSX pushback. My P3D version is V5.2, my plane is PMDG737NG, and ActiveSky is also used. I found that I can only call pushback service when I just get in the game, and it's very normal. But as long as when I finish the cold&dark, I call the pushback, I can see the models normal loaded, but the tug just don't come by, so the pushback menu can't show up properly. This problem also shows when I use the on board button, luggage service is normal, catering service is normal, just pushback doesn't work. I'm pretty frustrated now, hope you guys have a solution maybe.
