Playing Dwarves in ME and was allied to Barak Var. I noticed that one of my Lords could not move. I realized that my Ally Tunneled underground and landed on TOP of my lord. now my lord is unable to move and attack the nearby settlement or the enemy troops. The only way for him to move is by tunneling himself away. I find that highly inconvenient that you can land on top of a lord to prevent any movement.
My Lords name is Kazador Dragonslayer, and allied lord who landed on top of me is Mordim mattockwaz. I know that Tunneling prevents it when a player does it, I had no idea that your allied AI can just "block" you like that.
