I've noticed that some mp which outer polygon is formed by several untagged ways (e.g. [1] [2] [3]) do not appear in my maps (neither with default or custom style), only inner polygons are displayed. If I add relations style file lines like these: highway=pedestrian & area=yes {apply {add highway=pedestrian; add area=yes; add name='${name}' } } landuse=village_green {apply {add landuse=village_green} } leisure=garden {apply {add leisure=garden} } leisure=park {apply {add leisure=park; add name='${name}'} } then outer polygons are shown in the map, but inner ones disappear. Probably I missed something about mp, but don't know how to get these multipolygons correctly rendered.
