Hello,

Recently GSX has been acting really strange. Whenever I open the parking configuration tool in the GSX menu and click the customize vehicle location option, the entire sim shutters and the the aircraft will zip around the map for a good couple seconds and then it will come to a stop in some random spot. If I press the F1 key to switch to another vehicle GSX brings me back to the gate but all of the ramp objects are either under the ground or completely invisible. If I repeat the process GSX crashes and will refuse to work until I restart the sim. The issue is not specific to any airport or aircraft. Any advice? Thanks!

Editing in GSX means the sim will go in to slew mode, when you then press a key to alter something P3D will register a slew input and your aircraft rockets off to somewhere unknown.

Option 1 make sure the parking brake is set

Option 2 delete key assignments, usually from hardware (button x) for slew moments i.e. left/right, up/down etc.

Understood, I've tried both options and am still having the same issue. The plane rockets off (this time it finds its way back to the gate), however all of the ground vehicles are invisible or underneath the ground.

I had similar experience, when I tried to add jetways. Always when after rotating them, they flipped back as I tried to move them into position. Also jetways dissappear at the airport suddenly and soon after Couatl crashed and I had to restart the sim. I stopped editing therefore and hope at least the airports using GSX remain usable.

After this I installed the update from December 7th but didn't try if the editor changed.
