Hello Andrezej, I read the source-code and it just looks for a node with a place-tag exists in a certain bounding box, expecting to find exactly one. This will fail if: * there are more then 1 place-nodes in the bounding box * the city is too large the the node is not in the bounding-box * the location does not belong to the city but the center of some village is nearby * the location is part of a place=hamlet or anything but "city", "village" or "town" It's also quite expensive to do a bbox-query like that for more then a few locations. So it's neither easy nor anywhere near reliable. It's just a quick hack that works in some cases.
