This happened several times now. Game crashes when I
move the ship with left or right arrow key fast towards
deep waters (dark blue). The ship doesn't actually
reach the dark blue square but I think I would have
pressed it enough times that the ship should have got
there.
I'm testing the windows version single player.

The cmd window shows this:

java.lang.NullPointerException

I'm also attaching the log file in case that helps.
