Someone probably broke the coastline again. It's easy to goof when editing
the lake shore.
I don't have time to look into it right now, I can try on the weekend if
someone else doesn't fix it first.

(And, I confess, I've broken the lake shore of Lake Ontario at least once.
I fixed it promptly once I realized the problem.)
