[Bug] End of turn drawing with Evocation

I play Aluneth, Evocation, deplete my hand of spells (from Evocation, so I have free spaces to hold the next round of cards), then end my turn, Aluneth draws 3 cards but the game thinks my hand is full even-though I have spaces (since the cards left-over from Evocation have disappeared) and so burns the cards which I have space for.
