My home province was attacked by a stealth army and the castle is now under siege. I've got a big army in the province next to it, but after issuing a Move order I'm unable to select Move and Patrol from the orders list - the option simply isn't present in the list!??! The castle is still there (only slightly dented from the siege).
I loaded another game for testing, but had no problems - Move and Patrol was selectable from the orders list after the Move order was issued. The problem has only occured in this game.
Anyone else had this problem?
