Yeah, no autosave will save you against a power surge. As for exact failed autosave, that's strange. Usually, the autosave should trigger on each zone/map transition.
If you are trying to swap out the save, shutdown the game and copy it over into the new folder. But if you are doing it with an empty save folder, it will be easier to just copy the entire folder since you'll need the shared global files from there aside from the numbered saves.
Thank you. At first, I couldn't run the previous saves, because I reinstalled the game and threw files from the previous one into the new game. I was about to get upset that I had lost 5 hours. But then I thought in the new game to create the saves that were the previous ones and just replace them. I managed to return a save that saved half if not more of the progress and overall I am satisfied. Of course, autosave might have been able to work, but when I checked its performance, of course, it had already switched to another save for 30 seconds of the game and I think that the previous progress could not be fully returned. But even with this result, I am satisfied. Thanks for the prompt help)
You're probably right, it's just that I'm not very experienced in this (file transfer, etc.), so I might have expressed myself incorrectly or misunderstood you. I first deleted and downloaded the game again, then tried to replace the save folder in it with my own, it did not help and the old saves did not appear. I had to create a new file save in the game and the numbering was the same as the old one. Then I just copied and pasted the previous saves into the current ones with file replacement, that is, file 6(2 minutes of the new game) to file 6(2.5 hours of the old one). In the game, it was displayed as if nothing had happened, but when I entered the save, the content that I needed was displayed.
You write that it's risky, I understand. But I had nothing to lose, besides, I duplicated the saves in a separate folder in advance, just in case. It's just that when replacing the saves folders, the game stupidly did not see the old saves, but saw the new ones. So I thought it was possible to replace the visible saves with the old ones that are not visible.
Somehow, I hope I explained it.
I'm not very good at English, so I used a translator, so I hope he was able to convey everything correctly. Thank you for your support and time, as a user of the game, I appreciate it. I wish you and your game success
