Achievement Bug Mafia Wars

By playing on the others Zinga's game as well until reached level six, we are able to earned the Achievement. But this time, my friends have strange situation, he got the Ace Up The Sleeve Achievement by reaching level 6 on Zinga Poker, but he never played poker. Strange, isn't it? He got that achievement after helping his friend on their Secret Mission. 


Here the screenshot of the Achievement that he earned.

And this is the info of his stats on Zynga Poker game!

Well, I hope that you could get this kind of Achievement bug as well. Just try to register the others Zinga's game as many as you can and help your friend on their secret mission more often, maybe that's the only way to get it.
