Is the scenery default or 3rd party. If it's 3rd party, has the scenery being disabled from jetway replacement in the GSX Config ? And, it's the scenery bought on the MS Markeplace ?
It's a 3rd party, non Marketplace scenery, everything disabled in GSX config.
I was writing this during flight, and after landing, the deboarding was strange too... Passengers left the plane floating and started walking in the into infinity.
After that without MSFS restart, (just GSX restart ofc) I reloaded the flight in LIME, same parking pos. But everything was normal, so I cannot reproducate this
