Hi guys,
I have seen several players mentioning that there's an issue when using a Booster in Candy Crush Saga on Facebook.
The guys in the Game Studio are aware of the issue and are currently looking into it.
You can help me out by letting me know which browser and OS you are using.
Please also let me know if this happened while you were playing a Sugar Drop level.
I'll update you as soon as I know more.
