So I was playing the game normally and found this duplication bug while I was taking a enemy down by a non-lethal takedown, he started teleporting and dropping guns all around the room, I couldn't run or shoot with my pistol because I was stuck in the takedown animation, I don't know if it is a random bug or if you can do it making some glitches or etc, just posting it here so you can figure out the problem.
Also, when you aproach a enemy in stealth mode and grab it to takedown, his neck...

Duplication bug found while taking down enemies in stealth mode and another issues...
