This brocken waterway http://www.openstreetmap.org/?lat=47.91616&lon=5.99519&zoom=17&layers=M is a clear hint that one of this adjoining tiles isn’t render since end of August when I changed the waterway. I though this should have been done long ago. I’ve seen this on serveral different locations. So when can I expect tiles to be rendered after something has changed?
I’ve once red that setting the dirty bit enforces a rendering. How do I set the dirty bit in Potlatch or Potlatch2?
Is there anywhere visible when a defined tile is rendered the last time.
