Actually, if you're *literally* sailing out of the besieged castle, I think that *should* be allowed. Any castle in a coastal province is probably going to be built on the coast and the besieging army will probably not be able to blockade the harbor too. (Unless they also have a besieging navy, but that's probably too complex to implement.) Flying and sneaking ditto. (Again, rules for midair interception and patrolling to uncover the departing sneakers are probably too complex to make it into Dom3. But if the devs ever change their mind about making a Dom4...)

But if you can use order-changing exploits to assign those same kinds of moves to troops that don't belong with them, then that's a bug.
