Hi,
this changeset has created a lot of errors in the OSM database regarding self intersecting lines:

https://tools.geofabrik.de/osmi/?view=geometry&lon=122.46984&lat=-4.02828&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=139836752

I have reverted it to fix those issues. 
Kind regards
Guido
