I have a few polygons (forrest) that I made a few years ago. They are rendered on some layers on mapnik. But in many layers they aren't. So it is some problems with them. Is there a good tool to see what's wrong with these polygons? The polygon is visible on level 8 and level 9 on osm.org (mapnik) but not on level 10-18. I discovered that it's visible on all levels with the Osmarender map. So maybe this is a Mapnik problem.problem. In this case I talk about the forrest on an island: http://www.openstreetmap.org/?lat=60.38138&lon=17.20959&zoom=15&layers=M
