Yes I’m pretty sure procedures needs to be special cased because we have ‘procedures only’ scenery dirs. Sorry.

Another option could be to process the ‘extension’ XML files (runway_rename, ils, threshold, twr) when building the NavCache, when the apt.dat path is known? But this would make the NavCache build much much slower.

The ground-net and procedures files are different because they add in new data, rather than overriding apt.dat  data

Kind regards,
