Hi Yessica25,
this changeset has created a lot of errors in the OSM database regarding duplicate nodes and overlapping/duplicate ways:

https://tools.geofabrik.de/osmi/?view=geometry&lon=-74.88155&lat=5.02458&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=134667130

I have reverted it to fix those issues.
Guido
