Ok, I tracked down the bug; it occurred when you typoed the name of a ship,
because I miswrote one safety check.

Any other ship bugs, continue to report to me.

BTW, we now have a very good system for tracking bugs, typos & ideas, so feel
free to use the appropriate commands - in general, this is the best way to
make me aware of an issue. If you see a report status change to 'Ignored' -
this is because I won't make the associated change. This could be for balance
issues, conflict with existing code, or even because it is something that is
already in the works. But in any case, it is nothing personal
