@eagl3 So the sheeps name is Fenton. Tried it again after validating files. Nothing changed. The bug still breaks my game.

I encountered this problem the first time when i finished a mushroom riddle (the one where you have to make all flames blue with stone circles around them).
I finished the riddle, walked through the portal and got teleported to the starting position. But the event did not end. Eivor did not say her line. So i saved and reloaded. Eivor started saying her line the moment befor the screen turned black. So i knew it was stuck. I did the riddle again. Again no voiceline triggered. So i spammed horn, cloak on/off and meditation until she said her line and the event counted as finished.
But since then i have the problem with all world events and i can not finish some of them.
For example i can not rescue the sheep (named Farlon or something like that).
I kill the wolves, but i can not get the sheep back since it does not respond to whistles because Eivor does not say her line.
Please help.
