Hi Sabering,
this changeset has created a lot of errors in the OSM database regarding self intersecting lines:

https://tools.geofabrik.de/osmi/?view=geometry&lon=21.88811&lat=43.30542&zoom=14&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Obviously you have changed the shape of an residential area to be rectangular. Can you please fix this?
Kind regards
Guido
