Found another bug:
To defeat Ashe in the campaign, the alternate win condition is to summon one creature of each element. Whenever I fight him, I summon one creature on my first turn and it gives me the victory. Happened 3 times so far, I did it as a Cleric, Machinist, and Dominator. Each time, I summoned, as my first turn, a creature from my specialist domain and instantly won.
I am completely responsible for this bug. It will be soon updated.
