Play Action Actuator not working properly (Blender Game Engine)

I am having difficulties with the execution of an Action Actuator I created.
In the logic of the game I got a planet on a first scene. I’m supposed to click the planet and that will trigger two things: a second scene that’ll show a planet rotating and a Plane that’ll be fading out from black to transparent through some keyframes established on its Alpha channel.
This fading color action is executed by having the first planet sending a message to a sensor in the second scene.
The thing is working fine when I play it on the Timeline view but when I start the Game it won’t work by times and when it randomly does is not showing the fading effect but abruptly dissapearing. Any suggestions?
