Please clarify what do you mean with "storage rulls": the conveyor belt luggage loaders or the container loaders ?
And, as usual, when reporting any problem, always, always, always include ALL the following informations:
- the airport used, if it's not default, clearly identify which scenery is
- the gate/parking used
- the airplane used
- the operation you selected in GSX (boarding, deboarding, etc.)
And, be sure to have the most current version: we released an update yesterday so, maybe you don't have it yet.
