***UPDATE***: if you wait more than 30 seconds in between reopening the GSX menu, it will trigger the issue.
MSFS version: 1.29.30.0
Aircraft: A310-300, no enhanced package installed, default livery
Airport: ORBX KBUR installed and purchased through ORBX app
Weather: Clear skies preset, 10am
Traffic: OFF
Addons: removed anything that uses sim connect
GSX custom assigned HOTKEY: "Z"
1. Started MSFS as noted above at KBUR Gate A4, Cold & Dark
2. Started Couatl64_MSFS.exe
3. Opened GSX menu via hotkey
4. Clicked "Customize Parking"
5. Ticked "Disable Passenger Bus" and Clicked "Customize Passenger Waypoints"
6. Moved the gate position to area where passengers will emerge and clicked "Enter"
7. Opened GSX (via hotkey) and clicked "Operate Stairs" (waited for confirmation for stairs completed but nothing showed up)
8. Waited making sure stairs are in position then opened GSX (via hotkey)
RESULT: Deboarding process starts without any input and "Loading" shown on GSX menu and continues even after deboarding and baggage offloading process has finished
Attached the log file and the created custom parking position file. I also tried using the SU10 option with same results.
