No I totally get that but what I'm saying is the configuration that comes with the PMDG in your latest update when I try to change the height of the stairs and the catering it doesn't save it it reverts back to default each time... that's what I was meaning sorry
Well, first you shouldn't have to change it to begin with, because they are already correct in the internal configuration, unless I missed something so, in that case, please report it.
However, it's possible you might be mislead by the change in altitude due to the different height of the airplane when it's normally loaded to when it's edited ? When you edit the airplane, the editor place it in freeze mode so it will sit on its static_cg. This is made to be sure the edition is in a known state that is not affected by the airplane ever changing height due to a change in payload.
What might seem confusing, is that heights *DISPLAYED* in the editor, are based on as distances from Ground, because that's a figure everybody can relate to but, their DISPLAY is only valid during editing, because at the time the airplane is staying on its static CG.
However, GSX STORES the distance in the GSX.CFG file as RELATIVE to the airplane own center of mass (more precisely, the 0,0,0 in its visual model), and that's precisely to prevent having .CFG that would only work if the plane weight in normal use was exactly the same as while editing so, you might think your settings haven't changed, but that might only be a result of that difference, however the change would work in normal use, because is not stored as an absolute value, but as a relative offset from the airplane center, the altitude above ground of points is only a *display* conversion.
This, unless you see completely different issues, like the .CFG not being saved at all, or some error writing to it because of permission problems, etc.
