so i have just finished playing a game of oddball on haven and a guy called (Stevie W x) just glitched through a wall for the whole game and was made invincible,please patch this 343 
There are a lot of glitches like this on all the maps
It seems they did what every game designer did, throw everything together to get it out sooner, and than when something like this does come up, patch it 
You can also do it on complex, in the back building by the wire fence. I only learned about this one from watching someone jump into it via theatre (yay)
The same thing happened to me last night, dude just vanished inside a wall with the ball and no one could hit him.
