as I stated, everything WAS working correctly the day before I made this update
There are only two possible explanations for this:
- You haven't noticed it before
OR
- Something else happened/was installed and, since it happened roughly at the same time as your GSX installation update, you think it was caused by GSX.
The ONLY thing the GSX Installer does to a default scenery, is to disable the default jetway model from the library file that contains it. The most catastrophic thing that MIGHT theoretically happen (which never happened so far), is the GSX installer might corrupt that file, maybe because it crashed while doing it. And, even in that case, the worse it would happen, is that you would lose some library objects of the default scenery, that's it.
The ONLY way to cause misplaced parking positions on an airport, is with a conflicting AFCAD for the same airport. There are no other ways to do that, and GSX doesn't touch or install ANY of such files.
My first step will be to uninstall the Level 2 Expansion and see if this makes any changes.
It won't change anything but, if it's useful for you to convince this couldn't possibly caused by GSX, then by all means do it...
