So I've been playing Revelations recently, and was told that I would have access to all the resource fields (gems and foodstuffs) of both Hoshido and Nohr. Currently I have milk (Nohr), crystal (Nohr), Lapis (Hoshido), and RICE (Hoshido). The amount of milk and rice I have is ridiculous, especially rice, which I have so much of I have actually begun to hate it. Is there a way to change the resource fields I have? If so, how? Or are they randomly generated in each playthrough/game? I need some help. I don't have many companions who play the game, so my ability to travel to castles is limited, and the lottery rarely provides me with anything of value.
Any help is appreciated!
