Warning, you will use your boosters if you uninstall your game or change devices
There have been so many posts here lately about players upset that they lost all boosters after uninstalling to troubleshoot or changing devices.
Boosters are stored on your device and do not transfer when you have a new installation of your game. Even synced games only transfer level and gold bars.
Since so many players seem shocked and distressed by this I thought I'd post this warning.
Happy playing and vote for sugar drops to come back.
