So when a player go afk while in a wave, then after the next wave if they still remaining afk, they would not be able to play again.

I was experiencing a duel loop today. I think if a player go afk in wave 9, and reconnect while the wave 10 begun, their units would be invulnerable in the duel after wave 10. The game ends in the disconnections, and reduction of rating. Anyone got this situation anywhere?
