Zombalam

I had just finished doing all the side quests except finding the glowing mounds on round 21 solo and the agarthan zombies started attacking the generator as per usual. I had my first down and when the round was nearly over I started re-activating the generators and every one would activate except generator one. When i press square the icon to activate disappears for a few seconds, no money is taken and no agarthan zombies show up leaving me without quick revive. If im lucky i can pull one from der wunderfizz. Has anyone else had this problem?

Correct me if I am wrong, but don't you need the season pass in order to play nuketown zombies? and wouldn't that make the prize for this contest pointless? Don't get me wrong, I love your generosity, but if you want to hold a contest like this, you should hold it on Green Run since that is the map that everyone has access to.
