E' vero per le cose corrette tramite i file .fmf da mettere nella cartella editor data. Altre cose invece vengono corrette anche sui saved games.
Copi-incollo dal link che ha postato MichaelHarden:
"To make sure the files have been applied correctly, go to the Champions Cup and EURO Vase in your saved game, and they should be renamed to Champions League and Europa League respectively. If you are in the middle of a save-game, German national teams will be populated in the next instance that players are called up, and not instantly. Club names (including the German ones) are only changed if you apply the editor data files before starting a new game. For a workaround if you've already started a new save-game, then please read the opening post of this thread."
