I dont understand, I've had GSX L2 for almost a week and did not have this issue. Now, in P3D 4.3 every time I try to dock or undock a jetway to the FSLabs A320, it disconnects power to the aircraft and the external controls options in the MCDU get greyed out and I cant even select them anymore. seems to happen at any airport and any parking spot. I could not find any forum post about this in the FSLabs forums. I also looked for something about this here and couldn't find anything. EDIT, I just tried to reproduce this at KSFO and it didn't disconnect power this time. However it did happen at KJFK and MDPP. I'll try other aiports and see what happens.
