Pretty much what it says in the title. My companion, a Stone Giant Lord, did the killing blow on the Ancient Stone Beast while the Beast happened to be passing through a stone wall (or standing in a wall, however you'd like to consider it.) It didn't give any messages other than the monster's death. Looking around, I never found the items I would have expected: the corpse and the Chaos Orb of Elemental Earth. I had a back-up save so I investigated further. Killing the Beast myself or letting my companion get the final blow didn't seem to make a difference; if the Beast was in a stone wall, no drops, and if it wasn't the drops appear just like normal. Also, mining or Wand of Digging into the space didn't help me locate the items. I'm wanting to say they didn't get generated, but, well, has anyone else seen this? Or can replicate it? I have a save file of Ted the Human Farmer about to kill the Beast, so it should be easy enough to demonstrate what I am seeing.
