I'm quite confused as to who you are referring to by 'he'. If you meant Moukoko, which is the player I want to register but cannot due to age restriction in the first place. He is indeed not in the base game, but I have added him in through a editor data.
Hey I'm fairly new to FM and recently Bundesliga changed its minimum player age to 16. I wanted to change that in the pre-game editor from 17 to 16 but can't find a way to do it by going into competition ----> Bundesliga. Is there a way to change the League Rules in the editor? (Eg. Amount of Subs? Minimum Age?)
