Opponent conceded, then abandoned match. I was forced to wait through the entire time out for "Side Boarding," more time outs for them to "select" their opening hand.

Isn't it common sense to force the concession when a player wastes the entire sideboarding time out, without taking any actions whatsoever.

I really hope this gets addressed soon, because it is extremely annoying and ruins the gaming experience (though, I doubt it. This has been a common complaint among players forever and absolutely nothing has been done to address it).
