Hello, mkarau;
I noticed you opened many streets from status under construction to operational.
Examples:
https://www.openstreetmap.org/way/402014054
https://www.openstreetmap.org/way/478357941
https://www.openstreetmap.org/way/478357940
https://www.openstreetmap.org/way/65596630
https://www.openstreetmap.org/way/478357939
Also, you removed some nodes from this street:
https://osmlab.github.io/osm-deep-history/#/way/471889984
that's led to this street becoming disconnected from any street

Could you please provide us with the source you used to open these streets and fixed this issue please?
