[talk-ph] Rivers drying out in Palawan ?

[Rally de Leon]

Totor,
Maybe it's just a rendering bug. This is noticeable on streets and
locations of "place=town" POI's.

I have a feeling that some layers are assumed by the renderer to be
matured edits on particular zoom levels, thus remain old, constant or
obsolete.

Eg.: Pandi-Angat Road which was converted to Primary Road about a week
ago, remained Secondary Road (orange color) at following zoom
level=12:
http://www.openstreetmap.org/?mlat=14.9018&mlon=120.9869&zoom=12&layers=M
if I zoom-in by one step, the Pandi-Angat (primary) road turns to red
color --- the updated data.

Also notice the different location(s) of Santa Maria, Bulacan (town
name) in that vicinity at different zoom level. (old data is probably
the geographic center, the other one placed near poblacion)

But it looks like it's happening in reverse for rivers (palawan
example). The problem happens when we cross zoom=12 (or zoom=11?)

Cheers,
Rally
