Any troubles with Reach?

I’ve had troubles with Reach in the past with lag,recruit glitches,population counter to 0 and most of all on infection several times i’ve headshoted a zombie and they didn’t die.
Today i was on infection on powerhouse when a zombie jumped from a building straight at me i’m dead sure i headshoted this person 4 or 5 times and they didn’t die then they killed me.There’s also times where i get traced back to previous position due to lag.If you’re having troubles please tell.

You may have connection problems. There are also cheats on halo reach. I never have them problem in the game.
