I've had a battle that took place for atleast 2 turns, after first round at the turn, i moved my units to the shore to slow down enemy ships, then i've noticed that in doing so i've left open enemy reinforcements spawn point, tried to move in to block it but my units then got stuck in "performing a move". They couldn't move after they had to go through this tile even though they didn't exactly move into this tile. They couldn't move anywhere even though they had left movement points. Other units could get bugged in such manner aswell.
So i reloaded the save point, it did nothing to help me. Even though i've surrounded this field, enemy horsemen STILL (last time aswell) did not spawn. In doing so they enforced me into ending this war. (I was simply stuck, and didn't want to go back to resolve another long turn of combat and just hope that enemy wouldn't bug in another turn another time) I couldn't skip this battle aswell using auto resolve.
