Incomplete saves needed (Assassin's Creed: Liberation)

Please discard if anyone has 40%, 50% or 60% saves.
My saves crashed when I completed more than 50% of the game. After the mission with the second part of the artifact. It’s reluctant to go through again, but 100% saves are offered everywhere, but you want to go through something that you didn’t pass. Help if there is, maybe someone is in the game now.
Thanks.!
