Seems that the names on polygons (and some points) that also have an icon (such as amenity=library and such) are disappearing from the mapnik layer.
Case in point:
Last week this rendered fine with both the library and the name "Robbins Library", but since the tile was re-rendered the name disappeared. This is also happening with new tagged polygons.
(the ticket that created the icons in the first place). Anyone else seeing this?
