First of all I have updated GSX and there is an intelliscene.cfg dated 1/8/18 in the Aimobjects folder for the 2 variants of A319 and the single variant of A318.
Now, earlier I started a flight and everything worked as expected. Servicing, refueling and Pax loading completed with all vehicles lining up with the relevant doors and everything was good.
I then departed using the GSX pushback - still good.
Made the flight and paused it while I kept the family happy and had dinner with them.
Came back to the flight, unpaused and completed it to the destination.
Landed, set the parking spot and taxied to the stand.
Requested deboarding and the stairs di their job correctly but the loaders did a strange shuffle around and under the fuselage then unloaded.
I called the updater and re-intsalled GSX. Started the deboarding procedure and this time GSX performed as expected.
Am I missing something?
