@buttercabra Upon further playing it also happens upon loading a new world such as going to Asgard or Norway.

There is a mission in which you have to help a man in Cent count stones that seem to be changing their amounts. After telling him a few times and counting different amounts of stones the screen started to change color as intended for Eivor to trip out or something but then my screen went black. The compass and all UI was still working including moving around and attacking ( I could still hear all normal game sounds and could move around). I thought this was part of the mission that I went blind or something but it went on a while. It was fixed by changing Eivors gender but then the mission broke and there is no way to end it. Also every time the save-game is loaded no matter the location, Eivor starts tripping out again with washed out colors until the screen goes black until I go into my inventory and then change Eivor's gender to fix it. I can still play the game perfectly after this but it seems that mission is bugged for me.

Just a bug report, not urgent but I thought I should report it.
