Other player played "Raise the past" and put a lot of creatures with synergy on the battlefield. This created a situation where the game went into autoplay. The first player ran out of timeouts and got the warning that unless another action was taken, the game would end in a draw. As the autoplay continued, I then received a warning and my timeouts were used.The autoplay continued (as both player couldn't act) and the situation repeated itself, with unknown timeouts being used by both players and warning being issued time and time again. Eventually, the autoplay resolved itself but instead of creating a draw, I was given a loss.
