Sometimes it will almost load then go back to warzone and warzone assault menu…
Get into to a game and then a little while passes and booted. Can’t do anything stuck on a screen where I can only look at friends and past mission stuff. Getting so pissed…
Does it say why you’re getting kicked?
Or does it just crash to the Warzone menu?
I`ll be in like half way through the game or at any point and get booted… like why! 
Better be careful dude, same thing happened to me last night and I ended up getting banned for a few minutes. Apparently the update has changed it so that it counts the servers booting you out as a quit.
