For me it's already over but if i can save someone it'll make my day a less worst than it is.
IF YOU PLAY DIFFERENT SAVEGAME, DO NOT USE THE MANUAL SAVE, I REPEAT, DO NOT!
I finished the main story, i was power 315, asgard and jotunheim done. Was starting to go after order of the ancients. But i started another game with female eivor just to show my friend what it was like. So before starting i MANUALLY SAVED MY BIG GAME so that i don't overwrite it with auto-saved and quick saves.
i started the new game, played for like maybe 2 hours THEN i decider to switch back to my BIG GAME. But i told myself if my friend come back she will like to continue her game, so i've CREATED ANOTHER MANUAL SAVE, i didn't overwrite i've choose the button for a NEW MANUAL SAVE, BUT HERE's THE DEAL
INSTEAD OF CREATING A MANUAL SAVE 2 IT CREATED A MANUAL SAVE 1 (but my BIG GAME WAS ALREADY MANUAL SAVE 1) so i told to myself, maybe it means it it manual save 1 of the other game. But then i loaded my manual save 1 (big game) the one that was wrote 70h and the quest was chding the order, but when it loaded i was still in the 2h female game. So i told to myself ah its not bad its just a bug i will reload my game back, BUT NO THE TWO [censored] MANUAL SAVE WAS AT 2h now. So i was like nah maybe its visual [censored] or something. So i reload it, still the same thing, so at this time i was [censored], i turned off the game, i delete the local file then i synced fron the cloud, and guess what, only one Manual save remained after and it was the 2h one, so just like that i lost a 70h game.
SO PLEASE DONT EVER MANUAL SAVE TWO DIFFERENT GAME.
