"barrier=retaining_wall", quería decir.

Creo que habría que eliminar los ways osm.org/way/1199236331 y osm.org/way/1199236332

En las fotos aéreas no se aprecia que esa forma esté en el estadio (y en OSM la política es no dibujar las líneas pintadas en hierba, por ejemplo).

Pero incluso si se dibujasen, habría que hacerlo correctamente, y no marcando las líneas como "barrier=wall" puesto que no son muros reales.

Thanks for pointing this out. Someone else fixed it, and I had missed this comment, sorry. It seems the editor pasted tags from a road I had copied or a preset, and I did not realize it when uploading the changeset.

The Post Office tag was removed, and a note added to prevent this issue in the future.

I edited this when I visited. Just so I do not edit it wrong when I fix it, you mean that the number of the currently mapped post office is 109, instead of 111, right? Or that the building with number 111 is not the post office (since it would be in number 109)?
Sorry for the mistake.

Jan, I do not think that the note "Buy your bitcoins HERE" should be part of the node data. From the tags, this is a cafe, so I do not understand what the Bitcoin not has to do here.
Thanks

Thank you for double checking this and undoing my incorrect deletion, based on the imagery, and no visual evidences of the aerodrome

According to the wiki, ideally a relation should be used, including an area before the speed_camera and a little bit after, in which speed is "enforced".
