Ultraxion bugged in new patch?

After downloading the new patch to my PC today I tried to complete my daily quests with Herald Shaman as they all had herald boosts. Imagine my surprise when I played Ultraxion against my Priest opponent to have my game crash the second Ultraxion hit the board. OK, no problem, I’ll just reboot the game, that was all I could do on my turn anyway. I get back in and the Priest has taken his turn, and at least Ultraxion actually played onto the board, so now I can attack with it… the second I click on Ultraxion the game crashes again. So I skip my turn 7 and when I get back the game is basically over as the Priest has developed.

Is this just happening to me? I don’t fancy throwing another game to test whether it will happen again…
