Hi Umberto. First time trying ConcordeX with your program. All worked well (fuel/catering/passenger loading) except no loaders of any kind appear and when baggage trains appear they just loop around driving sometimes THROUGH each other and then drive away with bags still in the carts. I then receive "boarding completed" but no baggage has been loaded. Test airport NTAA default AFCAD ...but I changed gate numbers. This is a "HEAVY" gate configuration and tho I call it Gate 3 (numbered East to West) it is index #2 in the AFCAD (I did not change the indices). I have no custom GSX file for the aircraft and the gate is set as default GSX setting except NO BUS.
