Star Gazer. I just got all stars. I got the2 hours but not the 6 hour color bomb.

I won the weekend tournament which gave me 6hours of free play. Then I finished collecting stars for Stargazer and was supposed to get 2 hours free play(which I did get) and 6 hours color bomb which I did not get. It would have been perfect with my free play and color bomb to be at the same time! But no color bomb.
