Hi,

Thanks for your contribution! However I have few comments / concerns: 

I think there's few problems with this changeset. First it's missing changeset comment, so I don't know what you intended to edit here. 

Secondly, this changeset spans from norway across almost the entire russia. Ideally changesets should be local, a lot more local than this.

Third, there's bunch of nodes with no tags in them (and they're not part of a way). Such nodes serve no purpose, and shouldn't be added. Examples: 12385078560 and 12385078528

Large geographical size can happen if you accidentally upload some "old" data in JOSM - it happens to all of us sometimes!

For the nodes without any tags, you can try using some tools to find such nodes:
