Timer / preserve scene bug? One scene to another then back problem! HELP

dereklarue

In my main game scene i have a timer that does something every few random seconds, i have another scene that is used like a pause screen. When i go from the game scene (preserved) to the pause, then back to the game, the timer does not work anymore.
Either the timer or preserve scene is bugged / broke. Hope to see it fixed soon...
Its the only thing stopping me from putting my app in the app store...
