I’m having the same issue as stewart. When using the Carenado Phenom 300, I do the boarding procedure, the bus comes, but as soon as the green boarding message on the top of the screen shows up, everything freezes in GSX. The baggage carts stop, the bus is just spinning it’s wheels in place, and the sound of the bus & baggage carts engines can still be heard, even after closing P3D to desktop. When I Ctrl-Alt-Delete, I “end task” on Couatl engine, which stops the sound. When I tried it with the Citation Mustang, nothing freezes up, but there are no visible passengers or crew exiting the bus & van. It’ll say “crew boarded” and “passenger 1/4, 2/4 etc boarded” but there’s no animations. Is that because it’s a business jet and not a commercial plane? And I don’t know what the issue is with the Phenom. I saw that it’s not listed as “supported”, but it worked fine with regular GSX. Anyway, I hope this helps you with getting the bottom of the issue. Thanks!
