last night i have drawn in JOSM some streets that i’ve done with my gps, and now they’re gone. i don’t know what happened

also, about 2 days ago, i drawed other streets in josm. with josm if i download from osm, they are shown, but on the site they are not. i read that the time for processing is about two days.

Mapnik renders data once per week. Osmrenderer renders continuously, and has delay differing from few hours to few days, but sometimes it does not notice that tile needs to be rerendered.

Do you know why Osmarender doesn’t notice this? Any examples?
