While playing in a kamagawa premier draft I went second, played a red 1/1 haste artifact creature. My opponent responded by playing a 1R cost instant to do 2 damage to a creature and the game froze. I waited about 2 minutes and the exited out of the game, restarted my PC and then loaded the game and was stuck on a match pairing screen for 6 minutes. I exited out of the game again and restarted the computer again and restarted the game and it opened to a match loss and rewards to end the draft. This is the second time something like this has happened to me.
