here is the game name incase you guys store recordings of games "You entered CIDP (munkeyxis)" In the campaign battle called Citrine Temple Antechamber a Frost Sprite by the name of Zero shot his allies with Cone of Cold. I think this is an AI bug because there was no benefit from him doing this, my characters were nowhere near the attack and only enemy (Zero's allies) were even in target range. I've attached a screenshot highlighting the derpie AI.
Ah, that looks like another problem with cone attacks. A few other examples have been reported in this thread: http://www.cardhunter.com/forum/threads/ai-misfires-cones.2036/
