When creating a new place, sometimes the generated geocodes are wrong, maybe be cause it cannot understand the given address or maybe because there’s some special characters that breaks the site. In those cases, the geocodes will generally end up in a fixed place for a given region, where all those broken geocode places will pile up.
Please copy/paste post these geocodes here when you notice them so it will be easier to find places set in the wrong location on the map, with the city/region/country involved.
