Animation Playback

Hello,

I am playing multiple animations with different action actuators on the armature of my character (i.e. one actuator for all the arm actions, another for the leg ones) however there is a problem, which is probably best explained with an example:

I play the animation to take out my grenade weapon.
I play the animation to take out my rifle weapon.
I try to play the animation for taking out the grenade again, but although the frameprop shows the animation as running, it will not play again.
Any ideas as to what’s going on and how I stop it?
