Alright, nevermind. Seems like your edit is an attempt at fixing the issue I've described which was apparently caused by previous edits. Sorry, I'll revert my revert.

Reverted. I can only assume the complete breaking of the road layout itself is an accident?

changeset/167677856

It'd make more sense to keep a hierarchy system in place for subareas, i.e. admin_level 8 is only a subarea of admin_level 7, which is only a subarea of 6, and so on. So the four countries would be subareas of the United Kingdom, but not any of the counties or civil parishes.

Why did you replace a section of road in the middle of the United States with an untagged way?

Small edits in Dundee, but then edits all the way in Myanmar? Where did those come from?

A couple of addresses added to houses in Germany... then a pond all the way in Canada? osm.wiki/Changeset#Geographical_size_of_changesets

There is already a node tagged as City Lettings just south from this one, is this perhaps the same place?

Please be careful with how you tag things, as you had accidentally retagged a residential area into a building.
