New FireTeam Glitch Zombies cant get you

here are 2 glitches i found
1. You can jump on the elevator. Have a friend stand there jump on him tell you feel your self jump up a little more and you will stay there /
Another is you can get kinda under the map and Zombies can't get you you need a frined to stand on the Generator then jump on him and keep jumping tell it pushe's you threw the wall and then you will fall under
