Ok I tried to update the tags that were flagged as error by the system. Maybe I got it wrong?

fair enough

Actually, it is debatable whether this adds any value in a case like this with unambigous spatial relationship to the street in question.
happy monitoring

I appreciate that you reach out like this. Only my first thought was "shit I wasted a lot of time how stupid"
I might have a look at your resources

access to riot doesn't seem to work for me. anyway, was just killing time and will look for a different hobby now.

wondering though whether the landuse of the area with the new building should still be "commercial" and not rather "residential"

looking good!

did you delete the newly constructed building on corner Wezembeeklaan / O. de Burburelaan? In the real world, it's still there...

Thx for pointing this out. Sorry wasn't aware of this possible Attribute for the road.
