Hi BodhidharmaI,
this changeset has created errors in the OSM database regarding self intersecting ways (and displaced coastlines?):

https://tools.geofabrik.de/osmi/?view=geometry&lon=52.98251&lat=39.99252&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=159469201

Can you please fix this?
Kind regards
Guido
