I’ve been editing the map of the south of Nuevo Sabana Yegua, DO http://www.openstreetmap.org/?lat=18.4095&lon=-70.8393&zoom=13&layers=M
The point is that’s been a while since the nearest layers were updated with the changes that I made.
But the farther layer of the STANDARD view doesn’t change. If you choose “cycle map” or “map quest”, the layer shown is correct, but not in “standard”.
it happens because layers at different zoom levels aren’t updated at the same time. Try to refresh the image in the browser window (right click on the map). If it won’t help, you just have to wait, sometimes it may take few days or even weeks, especially for lower zoom levels. This is very commonly asked question here and unfortunately the problem still remains unresolved.
