It is a great game, however a little bit upset

The game is awesome. However, I am unable to complete the game in 100% because of a glitch. In the "Uzi Money" mission I am supposed to eliminate some guys with purple shirt but there is no guys in purple shirt. I read about it, and this glitch exists since Play Station 2. I would appreciate that at least the Uzi Money mission be fixed for iOS.
