Hi Verogisselle,
this changeset has created several errors in the OSM database regarding self intersecting lines, overlapping buildings and duplicate nodes:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-57.40962&lat=-25.33425&zoom=11&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Can you please fix this?
Kind regards
Guido
