If you perform a mission, such as raise defenses or move north, in the generals hut when you have no cash in hand but enough in the bank you only use one turn instead of the usual two turns.
This happens because it stops turns to secure funds from clunys hut so you only use one turn but the mission still completes.
Not a major bug but it could be abused.
Rawr, this one has been fixed so many bloody times now I don't know how it keeps reappearing.
Well at least you know how to fix it now.
Could it have crept back in when you added the message to tell us if our health is being restricted by our tax rate. Or any of the other messages?
