Having same issue today with a friend I have played in direct challenges in the past. Regardless of how we go about issuing the challenge (tried friend list with each of us issuing challenge and direct challenge both). I've tried 3 different decks, exporting and importing deck I'm trying to use, and changing things around in the deck. What is really odd is it removed the Bo3 half of my sideboard from my Bo3 I was testing out
