Hi AlejandroAlba,
this changeset has created errors in the OSM database regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-71.26047&lat=-42.82098&zoom=14&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=150986499

Especially way 78344849 is affected here:

Can you please fix this?
Kind regards
Guido
