In reply to A Longleat Boulderer:
Hi Fred,
They're marked in our backend as not-in-guidebook, so it appears that they were removed from the later guidebook for some reason, but I'm not sure what that would be.
Any guide that goes into the app has all the routes put in. Sometimes we put extra crags or sectors into the app that did not make it into the book, but we'd only remove things due to severe access-issues or whatever.
Very occasionally some route data is missed by the parser that extracts it from the page-layout documents, but in these cases it be lines would still be there, just the descriptions would be missing. This should no longer happen with newer books because we have many more automated tests to detect this stuff now.
I'll see if I can get hold of the author to find out about these routes.
