Not talking about it being difficult. But this last remaining goblin cannot be defeat. They been hammering at it for 2 minutes or so, at the highest speed, and my squad of 6, (1 cleric, 2 knights, 2 footman and 1 archer) cannot seem to even damage the enemy. Both footmen are level 6, have decent weapons.
Have survived past the helpful goblin explaining the story about his Kahn. This did not seem to be a special invasion.
Steps to reproduce:
No idea, beyond maybe having a enemy spawn with too high defense?
