Seems that mew VMAX crashes the game

Brysterj1

It appears that every time a mew VMAX is played, mine or an opponents, the game will no longer respond. I can finish my turn but the opponent never moves on their turn. If I wait, the game timer will count all the way down to 00 but the game won't force end. I have to either concede ( and definitely lose the match) or close the game and generally get counted as a loss.
