Undoing Lion's Eye Diamond causes Game Restart
I accidentally activated my lions eye diamond. I attempted to crtl +z to undo as it is a mana ability.
At this point behavior becomes unclear.
I believe the game attempted to undo by restarting the game and replaying up until the point of LED activation. At some point a dsync occured and the game crashed.
This resulted in a new game being started - complete with openning hands and mulligans. Additionally I was set to yield all.
This resulted in a quick and uninteractive loss where I was not able to take actions for the first few turns of the game. I lost the game and the match because of it.
Had the same thing happen to me in a casual game. Confirm this bug, same exact thing. It "replayed" the game when I tried to undo, then when I tried to undo the second time, it started a new game.
