Based on all of this, I would like to conclude: the situation is impossible to prove, and the moment itself is so subtle that it is impossible to replay it under the same conditions, since the fact of the event itself gives an advantage when attempting to repeat it. Therefore, my opinion is that the game should continue from where it was stopped, without replaying anything.

Given that there is a recording of the turn, replaying it by adding the hero's placement in the planned location is not a problem. I don't see any subtle moment here, except that the administrator should decide whether it is worth creating a precedent for replaying a turn based on this type of claim. Disconnects during battle are also impossible to prove, but decisions are made on them in one way or another when necessary. I also don't see any reason for a player not to appeal to the tournament judges as the first instance if their opinion does not seem authoritative to him for one reason or another. What is the point of creating unnecessary bureaucracy if an appeal will be filed regardless of the decision?
