A few bugs i've found:
1. Firstly, sometimes i can get 1 hit(downed) either with Jugg or without, mostly these are from the super fast zombies(but other times they don't 1 hit down you). Sometimes it's slightly better and you get downed with Jugg from 2/3 hits. Also, if you prone(with jugg) you get one hit downed no matter what. This makes the map very frustrating especially if this happens to you in late game. Sometimes you're running away and then all of a sudden you get downed.
2. The tombstone perk has a glitch where if one person has it and then all 4 people die. The game won't end but instead spawn in the next player(with the shortest waiting time) and only end when he dies.
3. There's an invisible barrier behind some perks(stamin-up and phd are the one's i've found) where if you stand directly behind it, zombies can't seem to hit you and thus makes you invincible.
Finally(not a bug) but it would be cool if you could include a weapon which has a similar effect to the ballistic knife in black ops 1 where if you shoot a downed team mate then they would get insta revived. I know there aren't any wonder weapons in this map(and probably for a reason) but if this special ability was included(like the explosives of third base and piss pump) then it would make the map slightly more easy and enjoyable since if you have a team mate who's down in late game; he will almost be guaranteed to down every time he spawns in at spawn.
Otherwise fantastic map with lots of replayability.
