MTGO did the thing where it reset the game and then fast forwarded to the point where we were supposed to be. But it repeated the process a few times then restarted the game from the beginning. At this point neither player could play, the game would just pass us through our turn into cleanup, at turn 5 i can play but my oppo cant.
For this issue, please submit at: https://mtgarena-support.wizards.com/hc/en-us/requests/new and select 'Report a Problem in your Event'.
Turn 7 for oppo and they can finally play
