Last night I purchased the CS757-300 Expansion for P3Dv4. Prior to that, when I called for the GSX catering trucks to service a 757-200, it did so perfectly, i.e. went to the correct service doors on the right-hand side. Take a look at this latest farce from GSX ;D Just about says it all that it does not recognise where the service doors on a Boeing 757-300 are! Anyone else with the same issue? A GSX aircraft configuration has to be made for the 757-300 as it was just released. GSX does not just automatically know where to put everything. This information either has to be made by FSDT and pushed via an update or created by a user and shared to the community.

I thought as it already knew what to do and where to go, perfectly, in the -200, and nothing has drastically changed maybe other than winglets, or overall length in the -300 but service doors are still in the same place, it'd still work as before.

Ah, well, will edit accordingly.
