Two bugs during my play:
1. When attacking the sound of the enemy getting hit and dying is already there. Afterwards the animation of the attack starts. It happened a lot with Tanris (if spelled correctly.
2. During the movement of my army towards the yeti camp (the dwarves disliked them, so someone has to kill them
) the game froze. The map could be moved but anything else (clicking on units, etc.) didn't work. Haven't verified whether it occurred again.
