Hello,
I had been looking through the forum to find a solution to just this problem.
In my case, the problem has only started in the last week or so. admittedly I have not been using GSX for a couple of weeks so the problem may have occurred through a recent update.
For me, I have pinpointed the problem to the Container loader and some of the passenger stairs. With the Aerosoft A320, I have the plane configured for baggage at the front and container at the back. When I call for GSX deboarding, the front conveyor appears as do the baggage cart and the container wagon, but not the container loader. The Conveyor moves into position as do the trucks and baggage unloading takes place, as described above with the containers floating down and onto the wagon.
With the passenger stairs, sometimes they appear and sometimes they do not. When they do appear, they are always the towed stairs (i.e. those not attached to a truck).
For me, this appears at Gate 5 and 6 (not checked others) at Exeter International (EGTE), by SX Airport design. I initially noticed there were no stairs at Heathrow Gate 421 with the iFly Boeng 737 as well, but these appeared after a reload (but they may have been the towed type I, cannot remember). I have removed all airport changes and the only aircraft config is for the containers for the rear. I have downloaded the latest full installer (On Sunday) and the vehicle Update yesterday and applied both. I also applied an update yesterday that GSX requested.
As I say I have not used GSX for a couple of weeks. This first appeared at the same time I was asked for the ground handler to be used. Previously it had always used the handler I had defined in the cfg files.
Regards,
