Follower: J'zargo
Place where bug occurs: Mzulft
The Bug: J'zargo gets stuck in a combat stance, he doesn't exit the stance when you sheathe your weapons/magic, and his weapon stays on his back in his stance (he just stands there with his fists; cannot even fight). A prior problem existed in the same location where J'zargo had no bodily animations; he just slid across surfaces. I couldn't find a way to fix this.

I'm unsure as to whether this bug has already been observed, but any solutions would be most welcome.

Did some more anolysis of the bug, it appears to be linked to after J'zargo engages in combat. He uses magic in the fight and sheathes his magic when I do when the fight is over, but when I draw again, he gets stuck because of his default weapon reappearing on his back; a hunter's bow (might be faulty follower AI at work with the default weapons conflicting with J'zargo's favored weapon, which is magic).

I've been getting the exact same issue, but with many different followers in many different locations, so it's not limited to a single follower or location. Fast travel sometimes fixes it, but when you'r on your own against 4 draugr deathlords 'cause your followers glitched, fast travel is not really an option. Even custom followers seem to be experiencing this glitch.

Is anyone else experiencing this? Can anyone shed some light onto what's going on and how to fix this? It's bleedin' annoying!
