Ok, I had a very strange bug.
Xbox one - Bangkok - 02.08.17
So I stunned everybody in the entrance hall with the gas, because I wanted to kill both targets. After killing Ken morgen, I went to Jordan crosses body location. But he was gone.(I'm not sure if he was dead/ stunned(but he must have been stunned, because of the gas!)) I checked the map, he was walking straight trough the hotel. Instinct said the same, so I tried to catch up with him. I failed, and had to stop at the map border. While cross was still walking, out of the map. Then I shot him a few times, he died, and fell through the "out of the map ground".(Which means that he wasn't dead in the beginning or he got somehow alive again...)
I hope you can understand what happened.
This was so strange, and creepy.
If you have any questions about the bug, ask me.
