Hi all,
I had added a border polygon for kosovo for easy extracting osmosis of kosovo points, the problems were many :

1. shared points with features.
2. duplicate points with other items.

it is finally gone.
osm.org/browse/changeset/2843120?node_page=1

Ideally we would have a border relation, not a way.

more to come. But soon we will have no duplicate points at all in kosovo....
