Attack animation overriding Stand Ready

Level 50
Dec 23, 2013
For some reason on my current model, when it attacks it doesn't just play the animation once, it overrides and repeats over the 'stand ready' animation.

So the tank fires its first shell (fine) but during the 'reloading' phase, it keeps repeating the firing animation, then actually fires again.

Any ideas why this is? I have added a 'Stand Ready' animation, its just not playing, and I have checked if it was the attack sound that was causing this, but can't make head nor tail of it.
