placing the bow icon over the enemy shows the "not enough action points" icon.
attacking anyway results in the following:
archer units step forward as if they were about to make a melee attack, goes through the attack animation, and then fires nothing but air. champions simply move towards the target square.
reload does not solve the problem.
I hope to hear something soon, because the game is currently unplayable without archers. (equipment good enough to go toe to toe with the bigger baddies is currently prohibitively expensive and mana regeneration is too slow to be an effective substitute)
