Listen up guys, this may sound a little out there but in the event of a Zombie Apocalypse your computers and/or devices may be forced offline therefore ending/disrupting your current CC run.
The only way to protect yourselves is to use the Perfect Idler Cheat:
Game.Unlock("Perfect idling") -Just pop that into your Console.
This will insure that your legacy lives on after the inevitable. It allows the game to play while you're away. Once we have devastated the Zombie Hoard simply log back in and you wont have lost any Cookie Clicks, in fact we'll be rewarded with a whole big butt-load of fresh new Cookies!
Note: Also works for more mundane things like loss of power or parental objectives to shut down the equipment.
You are now protected.
The USA has a plan in place for Zombie Defense and now so do we.
