It's a mod that adds the quest "Homecoming" to the game.

In the original game, you return to the village of Skalitz to bury your parents. On the way, you have to fight Runt, the leader of the first village. You have to kill him, otherwise, he will kill you.

Some of you did the same: you reloaded your save game, and tried to beat him.

You all did this: you went to bury your parents, and then you fought this Runt guy and immediately got smacked down.

Now it's time to learn how to actually combat this guy, only to discover that he is scripted to never ever go down no matter how much you lay the smackdown on him. He is slow, aggressive, and never ever protects himself, so it's no big deal, and a strategy that's easy to deal with.

The problem still is: he's scripted to never go down.
