Ok, I have played alot of zombies. I could list the levels I got to or the easter eggs I have done but I don't think I need to. Last night while playing with a group of 3 randoms on moon, several things were not right. The excavator that breaches tunnel 6 was supposed to breach in 60 seconds according to the voice but it breached at that point and trapped me. No big deal on taking care of the zombies but the breach was way off. The thing that got me the most was the Mule kick machine would not work for anyone on the map. It was like it didn't exist, no x prompt or anything. I know I could have just said forget it and started a new game which probably would have fixed it. I just want to see if anyone else has had issues with this not working or if it was just a once in a lifetime glitch.
