I am using the CLS A340-300 which has opening cargo doors in the belly. When unloading, everything works perfectly, the truck arrives, the ramp extends and baggage comes out and is loaded onto the baggage carts.
However, when loading, the baggage conveyor truck arrives but the conveyor does not extend, the baggage carts leave the terminal but just drive around the plane and disappear into the distance. Nothing loads.
Just to make it more of a puzzle, the catering truck arrives and elevates, unloads and departs with no problems.
Is this a bug, or can I adjust some setting to correct this annoying fault?
