Hello again everybody! I'm continuing exploration about that water bug, and I've found the limit of that effect, which is a huge 200km*2000km rectangle : http://www.openstreetmap.org/?box=yes&bbox=81.23549%2C54.060041%2C85.627667%2C68.841992 Some edge pictures are: East http://www.openstreetmap.org/?lat=55.27545&lon=85.627667&zoom=18&layers=M South http://www.openstreetmap.org/?lat=54.08514&lon=83.40566&zoom=18&layers=M West http://www.openstreetmap.org/?lat=58.858448&lon=81.23549&zoom=18&layers=M North http://www.openstreetmap.org/?lat=68.841992&lon=82.550755&zoom=18&layers=M I've found no strange geometry at the edges of the rectangle, and the edges do not always coinside with tiles edges (see this for example: http://b.tile.openstreetmap.org/18/190225/73869.png)
So the problem affects not only my city, but a huge 2000x200km area, and I have no idea how to locate the error. Any suggestions here?
