Came back to give a look at how this was going. Logged in fine, bought the new cards I missed from the bazar, all fine. Start playing some games to test things, the screen starts to flicker between 2 different game states when it is my opponent's turn, the only thing that is still functional is the resign button

This repeats for the next 3 games I try to play.
I decide to open the console, and there's a bunch of garbage there. To check what is actually related to the bug, I decide to reload everything and start from the beginning. Unfortunately this is the game's reaction to my attempts of login in again:
TypeError: false is not a function, https://etg.dek.im/etgify.js, 5, 8, TypeError: false is not a function
I'm still locked outside the game, so I can't give further feedback.
