Hi LeSharkoiste,
your recent edits have left behind a lot of errors in the OSM database regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=4.20543&lat=50.44397&zoom=12&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=140552608

Can you please fix this?

As you are using JOSM I am wondering how this could happen. May be you like to educate yourself about how to use its internal validator:

Kind regards
