wrong they do restore more/faster when they're in rest mode than being in normal or hard mode,back when i first playing this game i did have the same problem with u,back then my players were always in normal mode and it turn out they restored with really slow rate compare to when they are in the rest mode,u can check it your self.Also they do indeed restore each 3h.My players always have more than 70% condition,and i'm rarely use the rest pack (have 88 pack at the moment),only use it when the injury streak happen
