First of all, thanks for this good game.
Then, I'm not sure here is the good place to write about bugs. But I'll write here .
So, I've found at least one : after the game is saved after having obtained an agreement from a club for a player (so before giving this player a new contract), when we load the aforementioned savegame the signature bonus is systematically decreased to 0 (the game totally forgets the signature bonus... while the player normally wants of the dough!). Furthermore, when this number is equal to 0, it is systematically blocked and we can't increase it.
