Eorland Grey-Mane (Companions blacksmith) is dead in my Skyrim game, and I didn't kill him. WTF?!
I went to wait for him to buy some smithing supplies, and he never showed, no matter how long I'd wait. Then I noticed when I'd talk to the woman outside of the other blacksmith in Whiterun, she'd say, "I never claimed to be the best smith in Skyrim, that was Earland Grey-Mane, but now he's dead."
What the hell?! Seriously. How does he just die like that? He was one of my favorite NPCs in the game.
On a side note, when the game loaded after exiting a pub in Whiterun, a random homeless NPC fell out of the sky to his death. I wonder if the two are related? But I have never come across Eorland Grey-Mane's body, with the homeless NPC I was able to loot his body.
