(adsbygoogle = window.adsbygoogle || []).push({}); I've been trying to do the zombie rank duplication and it's worked out , however i can never make it stick , an error message comes up saying how that data has been corrupted and it resets back to the level i used to be , this happens after i've quit the game and gone back on zombies. Does anyone know how to make it stcik if you do pm me or just leave something on this post. Any useful tip would be a big help

Play a game for as long as you can before going off the game, also if you are the knife rank it's not likely to work.

ok thanks soldier i'll try it out
