Okay so I completed the Companions Quests.

The Silver hand killed off Skjor.

Well I was running around in Eastmarch, and I saw Alena the huntress and Farkas walking past me on the road. And behind them was Skjor, in a way.....

His had no clothes on, his wrists and hands were all curled up over his chest, his head was tilted to the right, his face was motionless, and he was in the ground. He was stuck in that pose, if you can picture him lol. All I could see was the torso and up. He was simply scooting along the ground (waist high to the rest of us) following Alena and Farkas. I couldn't interact with him. (talking or attacking). I would get in his way, he would simply slide around me by making a series of small 90 degree turns. lol

I eventually found myself going back to the Companions building, and much to my surprise, he's sitting there eating!
Everyone in the guild respects me as the guild leader, except for the creepy werewolf zombie guy sitting in the corner calling a whelp who still needs to prove himself. lol

Has anyone else had this or another funny glitch happen to them!?

That's creepy... I'v seen a flying deer, it landed in the lake near illinalta's deep.

Skjor came back to life in my game too, but he was walking around Jorrvaskr and not in... that kind of condition.

On one of my old characters, Skjor came back to life and lived in Jorrvaskr fully armored and alive. Broke the game for me in such a way that I restarted another character

PC only:

If Skjor revives for no obvious reason, just open the console, click on him, and type "disable" (Without the quotation marks).
He's gone afterwards, and never coming back. Seems more practical than starting a new game.
Save and restart the game client afterwards, otherwise steam achievements might be blocked (Not 100% sure about that though).
That did the job for me.
