I am unsure if this is also present before/during the Civil War quest, but after you complete the civil war quest (doesn't matter what side you chose) you cannot kill the 'leaders' of the rogue camps you encounter. I have tried bashing their face in, and all they do is kneel down then get back up with full health after about 5 seconds. I've even tried to console kill them, and they still do the same thing.

Is this bug going to be addressed anytime soon?

anybody?

It's not a bug (I think) they are all essential so unkillable, even tho the leaders of the war say they must be eliminated.

Either a bug or very questionable dev decision, far as I know it's permanent (pre CK anyways)

The logical thing (besides not making them essential at all to begin with) would be to make them killable when chosing a side in the war.
Or at least when the civil war quest chain is done, and the leaders blatantly tell you to wipe out any remnant troops you come across.
