Hi morago,
your recent changesets have created a lot of errors regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=128.10787&lat=35.09893&zoom=7&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=148533826

Can you please fix this?

Btw. you can avoid uploading such errors by using the internal validator of JOSM:

Kind regards
