A nearly perfect triangle of sea (the southwest vertex is missing a tiny slice) with its vertices about at:
40N31.573 101W27.493 near Imperial, Nebraska, USA,
49N29,936 97W59.876 near Carmin, Manitoba, Canada and
47N59.326 9125.395 in Snowbank Lake, Boundary Waters Canoe Area, Minnesota, USA.
These tiles seem to be involved in some manner:

The area has appeared in several down loads of the area during the month of February 2017.
I don’t know how to fix this myself. Guidance is appreciated.
If some one would fix it; that would also be appreciated.
