Hi rui228,
your recent changesets have added several errors to the OSM database regarding self intersecting and not connected (service) ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-8.26601&lat=40.65359&zoom=10&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

I have already fixed some of them during the last weeks, but may be you like to learn, how to avoid this kind of error.
Kind regards
Guido
