Oops - something went a bit wrong here.  At https://www.openstreetmap.org/way/1151620436 , this edit (I think) broke the National Park boundary https://www.openstreetmap.org/relation/2678988 by creating a hole in it - the small joining way https://www.openstreetmap.org/way/203258210 wasn't rejoined.  
Also, a gap appeared in the road that joined the BOAT to the west and part of the footpath to the south seems to have become road.
https://overpass-turbo.eu/s/1s5D is how things were on 28th Feb (you can click on the ways to see more detail at that point in history), https://overpass-turbo.eu/s/1s5G is at midnight last night and https://overpass-turbo.eu/s/1s5J is after I've joined it back up again.
Best Regards,
Andy
