Appeals Committee. Disputed situations in tournaments.

If the current logic requires loading and replaying a turn, it's bad logic. Either we play until a draw is reached, or we rely on the turn-breaking algorithm built into the HD mod. Otherwise, for the sake of saving 1 hour (this is a very optimistic estimate of the time saved from the end of restarts per match and the end of the turn limit), we risk creating a situation in the match where a turn is replayed, taking into account the huge additional amount of information obtained during the replayed turn.

So, the turn limit break built into the HD mod already gives blue the opportunity to replay the turn. The ability to move one turn with slightly more information is much more reasonable than moving a turn right under the opponent's nose blindly (without seeing the current position of the heroes, the state of the cities, etc.). Of course, ideally, this shouldn't happen either, and the turn limit should be broken preventively, but for now, this is the most adequate option for a soft landing.

P.S. and no, 4 turns per hour are usually not played on HDM1.
