Uncaught TypeError: Cannot read property 'deckname' of undefined,
https://etg.dek.im/bundle.main.js, 1, 76169, TypeError: Cannot read property 'deckname' of undefined
(2) When playing one of the first two daily challenges, on the 2nd game of the challenge, it seems to be trying to play multiple game instances at the same time and it continuously jumps between the multiple games within a turn.
