Thanks for that!
Does that mean that the ways that are part of https://www.openstreetmap.org/relation/13113383 could perhaps be moved to https://www.openstreetmap.org/relation/31640 ?
There are a few other NCN routes that have several pieces like this (not for reasons of length), but I suspect that someone might consolidate them at some point.
The milepost (if it doesn't get moved) won't be the only one that's no longer 100% accurate after route moving / renaming!
