Global spell tactics ?

[Chazar]

I am pretty sure that flyers cant fly away from a besieged castle, while stealthy troops can even if they do not sneak but merely move!

I am besiged in a current MP-game as caelum, and my seraphines can 'move' away, while my seraphs cannot. I think that this is also on purpose, since a stealthy unit should be able to sneak out and attack another province, hence the sneak/move should be independent on the starting provinve.

Nevertheless, I assume a bug: A seraphine cannot leave a sieged castle with assigned troops and she looses her sneak order when getting troops assigned; but she does not lose her 'move' order if she gets troops assigned - so I am curious whether my non-stealthy blizzard warriors could leave the sieged castle being led by the stealthy seraphine... (havent seen the next turn by now)
