I used this thread and just changed the value from 0 to 1 to see if it fixed the issue. Still the same. Cause of this so many of the quests are broken. Attack on whiterun, on attacking the jarl instead of dropping to his knees and surrendering, he dies and I cannot proceed with the stormcloak civil war quest line.
If you're talking about a bug where every npc isn't essential anymore then i have the same issue, it's been going on for months and I still haven't found a solution to fix the problem.
