Woho :-D Is there a reason for only 13 population on Tol Fuin?
Cool to see Isenmouthe there. Understand the reason why there is 10 castles there. Would make Mordor a harder place to invade, as long as orcs keeps at least some units at Minas Morgul (good that you have the garrison script). I just manage to siege Minas Morgul yesterday and whats sad is that even thought they had a full stack army in Minas Morgul they didn't counter attack me. No additional army came from the back to save this KEY settlement, I could just siege it until it gave up. They did give a fight at the last turn but then their army was reduced by 50%. If they only attacked when I siege, I would probably lose.
About Cair Andros, never seen this strange deployment issue on the vanilla map. Main issue in this settlement is space (since you can't play Jesus and walk on the water) and the common problem with that the enemy runs away in the start of the battle with no place to run to.
