Rollback saves on steam-license (Assassin's Creed: Origins)

I bought the incentive AK origins with the season pass immediately.Pumped already to level 12 and then in the game menu when you load seen item Improvement.Clicked it and began the 45 level.But now, the game is somehow not iteresno.If the level of the enemies is pumped as in the Odyssey close to yours then okay, but...is there a way to cancel this Improvement or to start the game from the beginning?I do not want to start again.And in menu game I see no point to Load the game.Play immediately begins from the point where finished the game
