The same thing happens when a unit with the immortal promotion gets "killed" -- the rest of the defenders all get pushed out of the city.It seems hidden units can't defend cities after all, or something. Whatever it is, my whole stack of defenders (32 units) are getting pushed out of my city when one can't defend, making the enemy take the city. (I think about 3 of the units where hidden)
EDIT: Seems like if a unit flees a battle defensively, it takes it's whole group with it as well.
Order and Veil can co-exist in the same city -- has this been changed from previous versions?
Dead undercouncil members still count toward the total number of votes needed. There were 5 members of the undercouncil and then both the Illians and Hyborem were crushed by a combination of Van Gosarm and Sandalphon/Basium. New resolutions said "(2 of 5 votes required)" even though there were only 3 members left. I assume the same type of thing would happen with the overcouncil.
