OpenStreetMap

Congratulations – you just shifted parts of London by 3352.6 km to the East all across Europe :)

I suggest maybe using a proper editor like iD instead of JOSM which is well-known for breaking data like this

<runs away very very fast>

The nodes shifted coincide with the corners of newly mapped buildings. This looks like a faulty mechanical edit or something like this to me.

Viewed in an improper editor: [url=https://ibb.co/Rb8Ztrt][img]https://i.ibb.co/Rb8Ztrt/Screenshot-20191107-194840.png[/img][/url]

Reverted in https://www.openstreetmap.org/changeset/76773501

Thanks \o/

this changeset (that i missed at the time, due to Having A Real Life™, whatever that is) is being discussed elsewhere, and what caught my eye is:

https://www.openstreetmap.org/node/108172/history

this shows an old node, long since deleted, and improperly brought back from the dead with this changeset.

i've also seen this behaviour with an improbable number of changesets in iran that recycle deleted nodes, adding rubbish tags such as gamification. i have not kept track of all these, but my recent memory is they appear to be from a legit version of josm, whether faked or from a malware plugin. i seem to remember analysing earlier gamification instances claiming to be from the bogus josm 1.6, but my dementia appears to be growing exponentially every day i awaken.

i just thought i'd mention this. no real reason. carry on.

If only Юрий Семенович could tell us what exactly has been done in JOSM within this changeset (plugins used etc.), the culprit could be hunted down.

perhaps we need a translator to ask him...
