Hi Max-Kritic,
this changeset has created several errors in the OSM database regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=1.28524&lat=49.35694&zoom=13&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=161246934

Can you please fix this?
Kind regards
Guido
