Seems like you watched a TDKPyrostasis video...

Its sort of awkward. I can hit them with blocks but not weapons, and only when crouching. I set it to novice difficulty and I was finally able to kill one of them with around 30 blocks and I'm working on the other two now. I guess I fixed it in a way.

Its not really game breaking, just annoying. 

Console.

I honestly don't know if this is the right section for glitches/bugs by the way. So these guys are always up here for me ever since I've finished the DB storyline. I can't kill them and it considers them enemies and they don't even attack me, just stand there. Therefore no fast traveling or waiting in Solitude. It also makes it so all the NPCs in the area not talk to me and say the usual "Those fools are actually fighting". Any tips on how to fix this?
