[Talk-us] Fwd: Lake Winnepesaki rendering issue

I have been experiencing what I think to be a error with the rendering of
islands in Lake Winnepesaki in New Hampshire. I tried copying the tagging
convention from Lake Champlain (Vermont/NY border), but it seems to render
the islands incorrectly as small lakes in two of the tiles in the
middle-bottom of the lake.  I don't know what I am doing wrong.

I have attached the link to the Information Freeware, OSM, and OSM Relation
Analyzer pages for your convenience.

Some details about the tagging of the lake:
There are 9 ways comprising the outer border of the lake with
"natural:water" as the tag and belong to Relation #63730 with the role of
"outer" and have a direction of clockwise
There are 152 self-contained ways (islands) belonging to the relation with
"natural:land" with the role of "inner" which as far as I know have a
direction of counter-clockwise

The relation is tagged with the following:
name:Lake Winnepesaki

I don't know if I edited the lake wrong or its a rendering problem or a
combination of both.
