• It's completely unclear from the red-rash. The problem lies in the forgetfulness (probably expert-level) of the players, not in the rule being outdated. And also in the inadequacy of the punishment – tech loss. Why not, for example, a fine of 1000-3000 coins with a game restart?
That's why changes to the rules shouldn't lead to excessive complexity. For violating the rules, even in the slightest – tech loss upon the opponent's request (it's not a given that they will demand it if you accidentally break the rules). However, the interpretation of the rules should not be ambiguous.
