FYI, from the March 14th, 2024 – Development Update:
Edit: This bug appears to be fixed (at least on my PC) in SU15 beta build v1.37.8.0.
- I followed the steps outlined in my original bug report.
- The Airbus A310-300 successfully loaded at Gate F22 at KSFO, cold & dark.
- Exited the flight, exited MSFS.
- Restarted MSFS, followed the steps outlined in my original bug report a second time.
- The Airbus A310-300 successfully loaded again at Gate F22 at KSFO, cold & dark.
Thank you Devs!
