I know Barebones liked to disappear, either because someone had killed him, or he'd go on a walk-about, but has the entire spawn vanished?
Morrae, what do you know about this...?
Shuttit, I ain't been hunting since the night we nailed Silver.
Barebones spawns the Headless, so no Barebones = no Headless.
I guess it's possible he just left the area entirely, as I know I was in the right area and I was there twice today for a good 15 or 20 minutes each time waiting around for him/the Headless to show up.
