szia d zsolt!
Először is – ez a módosításkészlet eltávolította a tagi módokat a 23096-ból – ezt láthatja, ha az alábbi "osmChange XML"-re kattint, és megnézi az XML végét. Látható, hogy az utolsó néhány kapcsolatnak nincsenek tagjai.
Ez persze nem magyarázza meg a történteket. Biztos vagyok benne, hogy nem volt rosszindulatú (tehát a balint36 erre vonatkozó javaslatai nem hasznosak), de valami elromlott, és ha nem próbálja meg kideríteni, hogy mi volt az, előfordulhat, hogy újra megtörténik.
Amikor feltölt a JOSM-mel, összefoglalót kap arról, hogy mit változtatott. Talán segítene, ha gyakrabban töltenéd fel, kevesebb változtatással az egyes changesetekben?
Üdvözlettel,
Andy

Hello zsolt d,
First things first - this changeset did remove the member ways from 23096 - you can see that by clicking on the "osmChange XML" below and looking at the end of the XML. You can see that the last few relations have no members.
This doesn't of course, explain what happened. I'm sure that it was not malicious (so suggestions of that by balint36 aren't helpful) but something did go wrong, and if you don't try and find out what that was, it might happen again.
When you upload with JOSM you do get a summary of what you've changed. Maybe it would help to upload more often with fewer changes in each changeset?
Best Regards,
Andy

Thanks!

You've also left "note:opening_hours:covid19" while deleting the tag that it refers to, which doesn't make a lot of sense.

way/168771637 has also closed and reopened under a different name.

Are you sure that node/313156653 is open? It didn't look it. See note/4068353 .

Hello - relation/6950474/history is a bit short of an international route? Was it perhaps something else?
Best Regards, Andy

Hello - relation/8453192 is a bit short of an international route? Was it perhaps something else?

The other correspondent also claims to be familiar with the local area...

Hello again Alex,
Andy from OSM's Data Working Group here. We've received a couple of messages from people also mapping in Ukraine saying that it'd be great if you were to use actual changeset comments not just "-" every time. Please do try and say something - it will help other mappers.
Best Regards,
Andy

Hello,
In this changeset you deleted the buoy at node/3815077900/history . I've undeleted it.
Also, please do try and use better changeset comments than just "another correction". It helps other mappers to understand what you're doing.
Best Regards,
Andy (from OSM's Data Working Group).

ah - ok.

For info this now appears at https://map.atownsend.org.uk/maps/map/map.html#19/54.29935/-0.89010 .

Just wondered - was leisure=park a typo on way/1238988328 or is it really a park?

Where there's a choice of words for something, and one is capable of being misinterpreted due to multiple meanings, OSM tends to pick the other - hence "sidewalk" is used rather than "pavement", despite the latter being the regular British English term (for historical reasons British English has tended to be used in OSM).
"pound" isn't a good choice for these features; there are too many other different things using the same word. Compare https://taginfo.openstreetmap.org/search?q=pound#values and https://taginfo.openstreetmap.org/search?q=pinfold#values .

Any thoughts about the tags for way/1238819902 ? I'm sure that people must have mapped them as something other than building.

I'd suggest mapping that as two separate features - the animal one as a pinfold, and the human one as some sort of historic village lockup (not sure what tags people use for those - you'd need to search through the data with taginfo looking for synonyms).

Hello,
You've changed this from a "pinfold" to a "pound", but it's definitely referred to as a pinfold locally.
More generally, the word "pound" is very generic and has many different meanings. It'd be better to stick to the original "historic=pinfold" for these features; if some (in southern England, perhaps) are referred to locally as pounds, and they really are different enough in function to tag differently, then maybe add "pinfold=pound" to those?
Best Regards,
Andy

Hello,
Was this used for animals, or people, or both?
Best Regards, Andy
