I was participating in the Saheeli event when this happened.

AI cast Devils’ Playground then end its turn. I played From Under the Floorboards and the game just frozed. Had to exit out resulting in a lose.

Edit
Just got out of a game as Koth of the hammer facing Liliana. She had 2 zombie token on the field from Revenant. And on my turn I cast Devils’ Playground the game did not freeze up however. I’m not 100% sure what caused it when I Summon zombie tokens with from under the floorboards earlier. So It may be caused by only having tokens on the field perhaps?

Just got out of another game that froze, which had tokens on the board from me and the Ai. I was on Sorin facing a Gideon support heavy token deck. Ai had a human soldier spawn from murder investigations buffed with various support. at the time I had angel of deliverance, archangel avacyn and played awaken Ondu raising, soon as the land tokens hit the battlefield it frozed.
