In immortal empires by turn 8 I had attacked Rapturous Excess in a failed ambush stance and defeated the lord on that turn which the  Ai had recruited a new lord new their base by turn 9 with remaing units. I defeated the lord and units again occuping the base and went to occupy it however even with 100% movement left I was left unable since the Karios was stuck in the ground near the base. Even after recuriting a new lord to capture the tower Karios is still stuck with 100% movement left.
