That something that you have to post on the Majestic forum. The issue is, since that airplane uses a non-standard flight model, we can't freeze it from GSX in order to prevent this, like we can do with any other airplane in FSX, because that airplane doesn't respond to the standard freeze command.
We added a custom variable in GSX, so any developer can check if GSX is pushing, so they can eventually freeze their own flight model for the duration of the GSX pushback, and this has been explained to Majestic a long time ago so, it's a very simple check of an L: variable to be 0 or 1, but only they can act on their own flight model, we surely can't freeze it from GSX.
