Lockup playing Ajani (post Devour in Flames fix)

Just had the game lockup playing Ajani. I had a Harness the Storm in play, had just finished casting a spell, Harness triggered and destroyed 3 gems, and then the game locked up. I was unable to check my hand and I wasn’t expecting it so I can’t be sure of the state of my hand exactly… I can’t verify whether or not Harness had returned a card to my hand. It was late in the game, tho, and I’d been using Harness frequently.

I had 2 cards in my hand full of mana when it locked up, Descend upon the Sinful, and Magmatic Insight. I wonder if Magmatic Insight was the problem since it hasn’t been converted to work with the new code for discarding yet?
