 The Detonator Bug has been fixed. The Detonator Bug in the Original Version   occurs when using a car bomb or Remote Grenades in conjunction with Infinite   Ammo (either with cheats or by getting 100% completion). After using the car   bomb or Remote Grenades, you are stuck on the detonator because the   detonator wasnt meant to have any ammo and the game gets confused when   using the remote with Infinite Ammo on.
