I don't think Adventurer's Guild is working. I have had a champion (Leanna) statined in a city with Adventurer's Guild for at least 100 turns (at least) and she has not gained 1xp. She has stayed at 69 out of 74 xp forever. I i know there is a 25% chance per season of it happening but i would think that after over a hundred turns she would have gotten at least 1 xp.
Another bug: Dragon's hurt themselves with their own breath weapon.
