I selected Zantonite (who is in play and active). I don't select to either attack or use his ability while he is selected. Instead, I select Antimatter, intending to use that instead. When I select Antimatter a selection animation appears as if I had used Antimatters effect. But instead nothing happens, and the game freezes. The time for my turn continues to count down but everything is frozen and remains so after 0:00 is reached, where it stays.
