I opened my game in the morning and all of my boosters were gone. I had not logged out or deleted the app, but my rank was at 1, the challenges were missing, and my boosters were gone as if I had just started playing (except that I was still on the correct level). I ended up deleting the app and logging back. My rank and challenges were back to normal, but my boosters are all still gone. I would like my boosters back as the app must have caused this glitch to happen overnight.
