Hi, lol, yeah. He just stays there lay on the floor next to his stall dead. I noticed he was dead fairly soon after meeting him actually, certainly before I downloaded the DLC. I vaguely recall fighting against some Drowners nearby. Whether they had anything to do with it I don't know.

Ok, here's a video of the problem. Everytime you fast travel to him, when you appear, you can hear what sounds like a sword slash off to the right, then you hear a groan sometimes, then you hear a body hit the floor. Then when you walk over to his stall he's dead on the floor...
Also doesn't matter where you fast travel to because if you slow travel to him he's dead when you get there.
