Ah; it seems that all the new updates have come with quite a few bugs.
So in my game, when a bullet is called to be spawned from a tank, it's is set to spawn at imagepoint 1.
It only does this 50% of the time. The other half it spawned from the tanks center (the object's position.)
So here's the game: http://www.mediafire.com/?zc9weg5yucd964s
Please note I'm talking about the green tanks, not the blue ones. The blue ones are supposed to have bullets spawn from the center.
Thanks for the help, cheers.
