Hi charles ,
this changeset has created errors in the OSM database regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=36.92156&lat=5.16108&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=138481055

I have reverted it to fix those issues.
Guido
