Hi r0x,
this changeset has created errors in the OSM database regarding self intersecting lines:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-58.26466&lat=6.04434&zoom=18&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=146834520

Can you please fix this?
Kind regards
Guido
