Hi racky,
this changeset has created several errors regarding self intersecting ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-5.65621&lat=9.45400&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=138041516

I have reverted this changeset to fix those issues.
