[Keepright-talk] Possible bug in islands

[David T. <no...@op...>]

I think Keepright's floating island finder will not find one-way
islands.  That is, an island might be connected to the rest of the map
by a one-way street, permitting traffic in to the island, but not out,
or visa-versa.

I don't actually know if any such islands exist, but it's got to be
worth checking.
