Hi Petr Bureš,
this changeset has created several errors in the OSM database regarding duplicate nodes and overlapping/duplicate buildings:

https://tools.geofabrik.de/osmi/?view=geometry&lon=114.35847&lat=-8.22821&zoom=15&baselayer=Geofabrik%20Standard&overlays=self_intersection_ways%2Cself_intersection_points%2Csingle_node_in_way%2Cduplicate_node_in_way

https://overpass-api.de/achavi/?changeset=157639020

Can you please fix this?
kind regards
Guido
