Oculus killed above a chasm will repeat falling animation each time you move camera to the place
If you kill Oculus (didn't try it with other flying creatures) above a chasm, Oculus body will fall down into it, but if you will move camera away and then return to the place, you'll see Oculus body falling into a chasm again. It can be repeated as long as a corpse exists.
Game version: 2.0.8f6
Game Version:
Steam Public Beta
Platform:
Windows
Update: After loading the game, I found two Oculus corpses levitating above a chasm and no longer falling into it. But I can't remember if I saw them each time I reloaded the same save.
