I beat the Bubblegum King challenge but did not receive my prizes.

I successfully beat all 5 levels in the Bubblegum King challenge on 2/7/16.  I was rewarded the gold bars collected for my "reign" but didn't receive any of my powerups/prizes or unlimited lives for the hour.

Just use the gold bars if you need boosters right. Then you can go back in and play the challenge again. That's the best part about it. It's all free and you get free rewards as well.
