Thanks - I've undeleted it and aligned it with imagery in changeset/172574575 .

See https://community.openstreetmap.org/t/automated-edit-of-waterway-spillway-and-man-made-spillway/136178

I don't remember mapping this one, but suspect that "usage=spillway" here is incorrect - it's a fish ladder.
Correct here would have been to do what you did at way/374759289#map=20/54.0337748/-1.2382691&layers=H and remove "usage" and leave "water=fish_pass" (rare https://overpass-turbo.eu/s/2cAG , but descriptive).

Hello,
You've changed the tags on way/949631071/history , the spillway adjacent to this hydro power station in Derby from "waterway=spillway" to "layer=-1;tunnel=culvert;usage=spillway;waterway=drain". I don't recall this has being underground, and wikipedia's picture from the opposite back suggests not either: https://en.wikipedia.org/wiki/Longbridge_Weir_Hydro#/media/File:Longbridge_weir_Hydroelectric_Plant_geograph-3480856-by-Ian-Calderwood.jpg .
I suspect you'll need to either revert your changes wholesale or check each of the 300 items you edited (checking with the local community or surveying) to make sure that your edits are correct.
Best Regards,
Andy

Hello,
This looks like a mechanical edit, and if so, should have followed osm.wiki/Automated_Edits_code_of_conduct . I don't remember seeing any discussion that said that you were going to do this. This is relevant because there are data consumers of this tag https://taginfo.openstreetmap.org/tags/waterway=spillway#projects - each of those projects has a contact mechanism (in many cases you can just raise a github issue to say what you are planning).
Best Regards,
Andy

Hello,
It looks like this edit or an earlier one introduced a gap in the Saxon Shore Way - https://overpass-turbo.eu/s/2cAp shows how it was a couple of days ago.
Using the previous OSM data and the LA rights-of-way data https://map.atownsend.org.uk/maps/map/map.html#17/51.27479/1.36797/H/P I've filled in the gap, and also one near the road.
relation/8864#map=16/51.27421/1.36877

Hello,
You've deleted the fence at way/694057190/history , but it still seems to be visible on aerial imagery.
Has it actually been removed on the ground since the last aerial imagery was taken?
Best Regards,
Andy

Thanks!

Merhaba Toygar Alak, OSM Veri Çalışma Grubu'ndan Andy.
Tüm değişiklik setlerinizde "Çok önemli bir yer" yorumu var gibi görünüyor. Her yer önemli olamaz herhalde? :)
osm.wiki/Good_changeset_comments adresine göz atın.
Saygılarımla,
Andy

Hello Toygar Alak, Andy from OSM's Data Working Group here.
All of your changesets seem to have the comment "Çok önemli bir yer". Surely not every place can be important? :)
Have a look at osm.wiki/Good_changeset_comments .

こんにちは。OpenStreetMapに存在しないものを追加しないでください（このコメントの英語訳には「表示されなくなった橋梁や路盤の線」が含まれています）。
これは以前にも言及されています。https://resultmaps.neis-one.org/osm-discussion-comments?uid=23230203 をご覧ください。
よろしくお願いいたします。
Andy

Hello, please don't add things to OpenStreetMap that no longer exist (the English translation of the comment here includes " Lines for bridges and roadbeds that are no longer visible".
This has been mentioned before - see https://resultmaps.neis-one.org/osm-discussion-comments?uid=23230203 .
Best Regards,
Andy

Hello crowntina and welcome to OpenStreetMap!

You've added a couple of odd things in your first and only changeset so far: http://nrenner.github.io/achavi/?changeset=172418737 .

OpenStreetMap is for mapping things that actually exist; perhaps you could explain the significance of "no king in acd" and "no king in ca" here?
Best Regards,
Andy

Hello,
It looks like the edit to https://osm.mapki.com/history/way/40971828 that removed node/385557097 from way/40971828 introduced a gap in NCN67 at relation/357215#map=20/53.3559866/-1.3857217&layers=H .
Clearly it's possible to cross the road on foot here, so I'd add at least a footpath here (with a kerb on it if there is one). way/303553186 is a similar one that I did locally to me a while back.
Best Regards,
Andy

There's a bug in iD that can encourage you to add ways to superrelations (here relation/5487294) rather than the local relation (here relation/5487293).
The other issue from changeset/172178406 is still a problem of course - clearly osm.org/directions?engine=graphhopper_foot&route=51.512009%2C-3.237576%3B51.512273%2C-3.237295#map=19/51.512475/-3.236980 is not a valid set of walking directions.

It looks like one of the node drags here made a dozen or so relations invalid, including "10709165 | Monkstown Parish". I've dragged that back in changeset/172414229 so that the relation is now relation/10709165#map=19/53.258073/-6.197441 , as opposed to self-intersecting (which made it an invalid polygon). This also affected "10709158 | Kilternan Parish", "13062149 | Glencullen ED 1901", "13061513 | Ballybrack ED 1901", "12491333 | Ballybrack ED", "12430312 | Glencullen ED", "4608457 | Tully", "2236209 | Kilgobbin" and possibly some others.
You can use Josm's relation validator to check relations (see @SomeoneElse/diary/406398 ) even if you don't edit relations in Josm.

Hello,
I think that something has gone a bit wrong here. There seems to be no way to get from one side of Ty Mawr Road to the other.
Imagine you're following the Cambrian Way long distance path relation/11661295#map=20/51.5121149/-3.2373653 - you'll see a gap.
Using a router to try and cross that gap you're directed like this:
osm.org/directions?engine=graphhopper_foot&route=51.512009%2C-3.237576%3B51.512273%2C-3.237295#map=18/51.511749/-3.237306
I'm sure that this is not really how it is - in practice the path from the Southwest and also the one northwest
osm.org/directions?engine=graphhopper_foot&route=51.512324%2C-3.2374196%3B51.5122606%2C-3.2373109#map=19/51.512675/-3.236990
actually do join Ty Mawr Road.

Andy
PS: Any questions, please don't hesitate to ask.

Are you seriously suggesting that the patch of grass way/587923070/history was named after https://en.wikipedia.org/wiki/Adem_Jashari ? Do you have any evidence for that?

您好，
四月的時候，way/733274217/history#map=17/21.983757/108.495998 是一座大型發電廠 https://overpass-turbo.eu/s/2bZb。您把它改成了房子，然後又把它刪除了。
您能解釋一下發生了什麼事嗎？
此致敬禮，
安迪

Hello,
Back in April way/733274217/history#map=17/21.983757/108.495998 was a large power station https://overpass-turbo.eu/s/2bZb . You changed it into a house and then deleted it.
Can you explain what has happened here?
Best Regards,
Andy
