My sapiens killed a mammoth and it vanished. The spears popped out a short distance from where the mammoth dropped, and I thought it had just glitched out of existence. Then I zoomed out and saw it levitating about a hundred feet up in the air, a small distance in the opposite direction from where the spears dropped.

It seems to be a graphical glitch; my sapiens can still interact with it just fine, though the interaction spot does NOT match up with the mammoth (no flying sapiens). The meat & woolskins drops by the interaction spot like normal instead of hanging suspended in the air by the levitating mammoth.

Its just. A little bit weird. To see a several thousand ton hirsute pachyderm miraculously suspended in the ether like a child's lost helium balloon. I have some screenshots, if those would help?
