If links dont open, blame the Elisa Eesti AS. I had situation lately where none of the wesrnordost.de links did not open. Eventually with StreetComplete devs we came to conclusion that its Elisa fault and not my devices or StreetComplete's since they host note photo links on westnordost.de server. Link opened for me but today already had one moment when it did not open.

Anyway, yes, the paths are separated by low concrete blocks which I thought should be mapped hence the note back when I passed there.
