Hello,

I have two issues with this changeset:
1.) why do you create a new relation (https://www.openstreetmap.org/relation/17953654) when a relation with same ISO3166_2 already exists: https://www.openstreetmap.org/relation/17903691
2.) the border is invalid, please verify the border with JOSM: the roles (outer/inner) for member ways are missing and the boder has self intersections
