I hunted Triath, the King and killed him on a slope in an Antiquarian Forest. His body slid down, but his position marker remained where he was killed. When I try to harvest him, my knife would make the proper sound, but no mats were released.
I tried exiting the game (main menu, and windows) and reloading. Neither worked and the corpse remains unharvestable, downslope from where it was killed.
