The sports area I am talking about did not have any playing fields, it was without the various pedestrian paths, the fountains, the trees, the fences, the gates. Without a note, no one knew of the absence of such elements.
in this case it is about distinct buildings but one next to the other, imported as a single block from government maps in osm. So the “building” area is wrong, I don’t know if a fix me or a note would be more correct.
