Today, after an update was installed on my console, I was super shocked as I continued my story and missed about 5 hours of gametime. When I tried loading a different save, it seemed like the newst one, was from 9 days ago (8 feb).

It took me quite some time to figure out I had savegames, dated 16 december 2019. When I took a closer look, that was actually my last save. So for some reason the date of the latest save files changed.

Fortunately, I could load the save and continue my journey. I would have been really annoyed to lose my progress. These kind of mistakes / errors / glitches are in my opinion unforgivable and evidence of poor and careless development. Not putting a direct blame here at Ubisoft, this could very well be the Microsoft Xbox Series X environment. It might be possible that the update terminated the quickresume valhalla session or something and by doing so changed the game save file.

I hope that this somehow helps identifying and fixing this issue. I also post this here, in case others have a similar issue and haven't figured out that the savefiles could actually be dated incorrectly. Cheers!
