same here, it is extremely annoying. I got half of the map in 1.1 - no mods, and my armies just cant get anything done because anything they take they leave it empty, the enemy just take it back within 2 minutes as armies are already working on a new objective and dont care about besieged place they just took a minute ago. Well, the armies just go back and forth between 3-4 settlements and do basically nothing. And I tanked the vassals I got 14 clans, 21K strength and they cant do ****.
