MKU Staff, as a whole, has decided to review the match score.
It has been shown from Mandarina de Schrödinger that the invalid FC was due to a typo while registering the given player (CarlozF).
The right friend code was 2851-8241-1432 instead of 2861-8241-1432.
The Rule 1.2.e.i.'s goal was to punish players not playing on the right account. However, it was clear in this situation that the right player has played the match. Also, on the old MKU registry, the given player was correctly registered.
It has been voted by a (large) majority (8 against 1) that removing the whole points to the given player would have been contradicting with the rule spirit, especially since the league moved to a new website, causing players to register again. Therefore, the penalty is removed.
However, I personally reminded every team representatives in Division 7 to make sure informations in registry were exact at the season beginning, which hasn't been done from Mandarina de Schrödinger, which caused a minor issue here. That's why I will add, as staff discretion, a -20pts penalty to Mandarina de Schrödinger.
The final score for this match is therefore:
Horizon 456 - 508 Mandarina de Schrödinger
I want to apologize, as a Staff member, for not following Rule 1.2.e.i. by the book, as it is penalizing Horizon here. Staff will definitely review the given rule section during the next off-season to clarify situations that could happen like this.
