[Ghoul Bounty Assassination Glitch]

I was running some ghoul bounties and got the assassination target stage, I killed the enemies to lure out the target and when he spawned in he seeming went through the map and was stuck under there causing me to fail the bounty. I apologise for my language in the clip, I was just frustrated because I had it happen in the previous bounty that I did and it was getting on my nerves, it also didn't help that I was tired.
