Why do my boosters keep disappearing?

Sparkles

My boosters keep disappearing. It's happened three times now. I've tried refreshing the game etc but it doesn't help. It's really annoying me, what can I do??

Did you pay for them? If so then you only need to go into the app and click on 'restore purchases' and it will add the paid boosters back to your game. Its in the settings section of the app (bottom left hand corner) 

I hope this helps
