Call of Duty: Black Ops III

Town of the Tormented
Game Ending On It's Own?
Hey, I've got to say I really enjoy this map. Its especially nice cause I have a lower end laptop and I can play this without too much lag or frame drops. I love being able to finally try to go for high rounds and completing an easter egg for the first time by myself.
I do have a few things I would like to point out
1. Does the perk by P-A-P ever run out? It seems to function like a quick revive, and most of the time, will keep my perks and weapons, though sometimes it doesn't and I will lose my perks. This is pretty rare though
2. While trying to go for high rounds today, the game ended itself twice, both of which I had gone down but got back up
2.1 The first time it happen was when I had gone down but I kept everything, and then shortly after the game gave me a game over screen on round 32. The next was when I went down, lost my perks and third weapons (despite having the perk and quick revive), and then, got some perks back, and then got the win screen on round 33

Is this is a bug or intentional?
