I don't know if this bugg is already fixed or someone already mention it. After you siege Storms End and win the "main" battle. You "pushed" the enemy back and fight them a second time inside the "castle hall". Me and my men insta die when we spawn at the attack in the hall. And then i had to siege the castle all over again. I won the main siege fight And pushed the enemy to the hall for the last battle (again) .... annnnd the same thing happend again me and my soldiers insta die and the enemy wins..... i tried to starve them out but i had to many men so i ran out of food.
