While sleeping, you can see the following:
a sharp bone dart slams into the King, dead center!
wtf???
Just ignore it as a player I think, just like some other things, you see it pop up while you are sleeping, but that doesn't necessarily means that your character sees it happen, or feels it.
Does this really deserve a 'wtf'? That makes it sound like some coder somewhere deliberately left it in there.
Why not just use the bug command in game and maybe someday it'll get addressed.
