Hi Marvin,
this changeset has created several errors in the OSM database regarding self intersecting lines:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-99.87310&lat=16.88458&zoom=13&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=155560804

Can you please fix this?

You can avoid uploading such errors by using the internal validator if JOSM:

Kind regards
