After Updating my GSX; I noticed that not all Aircrafts are showing the animated refueling
As discussed in many other threads, the new animated refuel truck supports only airplanes with a refueling point higher than 3.45 mt. We might add additional vehicles in the future, but right now, if you the plane you are using has a lower refueling point, the previous simpler truck will arrive instead.
even after configuration the vehicles are not placed correctly though the dialog box appear but the vehicles are not placed correctly
It's not very clearly what do you mean with "after the configuration". What configuration ? The airplane or the parking ? If you reconfigure something, it's best if you choose "Restart Couatl" after saving your changes.
