Hi Добавление дороги на карте ,
this changeset has created errors in the OSM database regarding self intersecting and overlapping ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=43.15887&lat=48.84436&zoom=14&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://tools.geofabrik.de/osmi/?view=routing&lon=43.14308&lat=48.83416&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas%2Cislands%2Cislands_car%2Cislands_bicycle%2Cislands_all

https://overpass-api.de/achavi/?changeset=145146537

As you may know, this kind of errors irritate routing software and looks ugly on the maps.

Can you please fix this?
Kind regards
Guido
