This is just a general warning message for ship captains - there is something
a bit off somewhere in the movement code, I'm working on finding a solution,
but it'll probably be a few more days before I can hunt through the code
completely.

The general effect seems to be that ships that aren't capable of flight try to
push themselves up onto land. This, naturally, is Not Good (tm). I'd advise
you to avoid cutting it close around land masses until I can figure out what's
up.
