For those like me trying to get this thing to work in P3Dv5... Install the original FSX version to a random folder, and move the terminal_receptions and jetway_library bgls to your P3D VIDP installation. No discernable performance difference and prevents the 'receptions' from disappearing.
You sir are a bloody genius!
For anyone having the same issue... I am attaching the FSX version of the receptions and jetway BGL's.
