[OSM-newbies] Finding duplicate node points near other nodes of the same type?

[Cartinus]

Use the revert plugin in JOSM to revert your changeset, but don't upload
the changes.

Load the area again, but in new layer. Make the changes you want in the
new layer.

Delete the layer with the reverted changeset.

Upload your edits.
