My crude understanding is that the mapnik renderer is given minutely diffs of the tiles that have changed during a changeset. Upon the next viewing of the changed tile a new tile is rendered and displayed. Occasionally a changeset is missed by the diffs and it takes that section being changed again or a re-render of the world to catch the changes, I wouldn't worry about it check it out on T@H (they're there) <a href="http://tah.openstreetmap.org/Browse/slippy/?zoom=14&lat=32.4719&lon=-110.807&layers=BF">http://tah.openstreetmap.org/Browse/slippy/?zoom=14&lat=32.4719&lon=-110.807&layers=BF</a> <div>
<br></div><div>As a side note, it looks like your current import toolchain causes lots of duplicate nodes. see the maplint layer on OSM proper <a href="http://www.openstreetmap.org/?lat=32.4719&lon=-110.807&zoom=14&layers=000BTTFT">http://www.openstreetmap.org/?lat=32.4719&lon=-110.807&zoom=14&layers=000BTTFT</a> figuring out a way to reduce/eliminate those duplicate nodes before upload, is probably a good idea.</div>

I'll give examples of a single trail from each set.<br>
