Hi Fidelis Assis,
your recent activities have created a lot of errors in the OSM database regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-41.66371&lat=-14.27553&zoom=7&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

Especially rivers have been affected.
Can you please fix this?
Kind regards
Guido
