Hi oneho,
this changeset has created a lot of errors in the OSM database regarding duplicate nodes and self intersecting ways:


https://tools.geofabrik.de/osmi/?view=geometry&lon=17.29371&lat=48.55170&zoom=11&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=146566553

Can you please fix this?
Kind regards
Guido
