What's the problem? In chess, draws can occur after the first move in tournaments, and so what? If players reach a situation in a previous game where a draw benefits both of them, on what basis can they be forced to play until someone wins? This is a common tournament strategy... I don't understand why they should even have to explain the lack of time or anything else...
Either the tournament organizer should specifically state in the description that a draw is only possible by the judge's decision, and if that's not the case, it's absurd to demand any save files when players mutually agree to a draw.
There are no "Sofia rules" in Heroes, so players can agree to a draw even without playing. At least because it's impossible to control.
In fact, in many chess Swiss tournaments, there's an option to "draw with oneself," meaning a player can request a 0.5 score without playing and without an opponent being assigned once during the tournament.
