@koskite Thanks! This actually worked for me. It's just embarrassing that Ubisoft hasn't figured it out yet.

Same problem for me. Can't get past the splash screen.

@ubi-borealis The same thing just happened to me. I'm playing on PC. I had just recruited my first Jomsviking and went on a raid. After the raid was done both autosaves and quicksaves stopped working. There is was no indication that it didn't work other than the save icon not appearing. I lost two hours of progress because I needed to go back to an earlier save, only to find they weren't there. I only use three main save slots that I rotate between.

I seem to recall the exact same thing happening i Odyssey from time to time. It's a bit embarrassing when the same bug is still present in the next game a few years later.
