Although I still think that was the wrong call and the game had progressed too far. But at the end of the day, if both players were happy with the judge's decision, then that's fine. If the judge made a call that one player felt was completely and utterly wrong, then there's going to be a problem.
So Parravon, allow me to ask then (and I mean no disrespect in doing so, but I'm curious how I would be expected to call this when I'm judging my next event) - if we assume that the game has progressed far enough that a complete rewind is a bad call, then what would be the right call at this point?
If I were the opposing player to the player who just largely benefited from this mistake, I'd feel pretty cheated if the judge just said "well, let's just put a stress token on the ships that should have been stressed" full knowing that red maneuvers had been executed illegally and that the current state should now be completely different.
You have no right to. It's is yours resposibility to make sure your opponent does not want to cheat you (intentional or not).
He missed it? Jugde should make him put those stresses and give him a warning that next time he will just loose the game.
You missed it? Shame on you.
No opinion about rolling back a game from me.
