Do you know any trick that can make the cargo door resulting closed for gsx, since it dosen't push back till it's closed, thing that I can't do at this time ?
I'm not really sure what are you asking, why you cannot close the cargo door, and which cargo door are you referring to ?
In any case, as explained in the GSX manual, if you want to set GSX to ignore a door's status, you can configure the door as "Door with no open/close checks" in the editor, so GSX won't check if it's opened or closed.
