Hello,
Along with quite a few other relations, https://osm.mapki.com/history/relation/2267444 seems to have been broken by your edits in the last day or so.
Previously it looked like this:
https://overpass-turbo.eu/s/2beU
and now it looks like this:
https://overpass-turbo.eu/s/2beW
An easy way to check for gaps in relations is, for every relation that you edit, go to that relation's OSM page (you can click through from your changeset). Here that would be relation/2267444#map=15/52.67545/-6.84360 - you can see (until somone comes along and fixes it) an obvious gap there.
Best Regards,
Andy

I think some of the separately mapped sidewalks in here are a bit incomplete - see for example osm.org/directions?engine=fossgis_valhalla_foot&route=53.634039%2C-2.815702%3B53.634007%2C-2.815523#map=19/53.634189/-2.814973 .
If it was me, I'd just use "sidewalk=left" or similar here; if you're going to use separately mapped sidewalks you need to make sure that you join everything up.
Best Regards,
Andy

After editing any paths involved in a hiking route relation (e.g. all the coastal ones!) it makes sense to check http://ra.osmsurround.org/analyzeRelation?relationId=77964&noCache=true&_noCache=on (where 77964 is the relation) so that it matches what is signed on the ground. There are obviously genuine duplications (high and low tide, whether paths across the ranges are open etc.) but there are some very dubious spurs still.

I've fixed a dodgy overlap at the north end of that which clearly didn't exist.
I've assumed that the inland path to relation/77964 as I presume that that is where that is signed and routed now (my GPS traces here are from 8 years ago and may not be accurate any more).

Hello - it looks like this edit introduced a small spur to the Wales Coast Path - I've split way/1390827060 so that hopefully it's contiguous again.

Hello,
It looks like way/1379326419 had been accidentally missed from NCN4 - I've added it back.
Cheers,
Andy

The woodland at way/148883959/history got deleted in this changeset. What were you trying to do?

Any idea what "building=s" is on way/252175919#map=19/53.269303/-3.914435 ?

What sort of building is a "seb"? way/1367284049 .

Hello,
Lots of the houses in this changeset are "building=semidetached_house100752" - I suspect that is a typo?

Andy

Some of these building values were odd - I changed them in changeset/165005490 .

Oops - looks like this added an extra bit to NCN425 4247567 here - I've removed it from the relation.

This changeset broke the Centenery WAy at changeset/163340221#map=19/52.502942/-1.472353 . I've fixed it.

Oops - way/1363664264 wasn't joined to the service road here.
I also filled in the gap in the Centenery Way.

Hello,
There seems to be a bit of an odd spur on a few route relations at relation/1832946#map=19/51.626375/-1.013466 . Is that a mistake and do they all go to the south, or is there a bit through the field missing?
Affected relations can be seen at https://map.atownsend.org.uk/maps/map/map.html#19/51.62638/-1.01347 .

It looks like one of these changes broke at least one relation - "12458163 | Kilconny ED". I've fixed it in changeset/163005426 - does everything still look OK?

Hello and welcome to OpenStreetMap!
I think that this edit might have introduced a gap in the Saxon_Shore_Way relation 8864. I've filled it in now:
relation/8864#map=18/51.384666/0.523991
It might also be worth checking the other bus route relations - way/1359466727 is in fewer than the way to the south.
Best Regards,
Andy

Hello,
I think that this edit might have introduced a gap in the Saxon Shore Way - I've filled that in in relation/8864 .

Hello,
I'm not sure what happened here, but one of the ways way/273992803 seemed to get added to some relations more that once - it looks like it was already there with role "outer", but was added again with no role, which seemed to result in the relations dropping out of a rendering database. I've removed the duplicates, so the relations should appear again tomorrow.
Best Regards,
Andy

Hello jajanja3,
There's a gap in the Saxon Shore Way at relation/8864#map=19/51.383975/0.507900 - do you know how it joins there?
Best Regards,
Andy
