Hallo, ich habe ein kleines Problem. Ich habe nun alle Errungenschaften von diesem Spiel geholt. Aber unter meinem Profil wird es nicht als "Perfektes Spiel" angesehen. Könnte dies eventuel behoben werden? Hi, I have a small problem. I have now gotten all the achievements of this game. But it is not considered a "Perfect Game" under my profile.
