There’s not much clearity how the sorting of the context.xml affects the sim. It seems to be relevant, which scenery is on what place. E.g. if the navigraph airac is placed wrong, it could interfere badly with scenery.
On the other hand MSFS just puts every new installed scenery at the bottom of the context.xml. And if you delete it and MSFS builds it again, it sorts the scenery kinda alphabetical (kind of).
