Hi @Sherri_Studholme All the boosters are saved locally on your device, so whenever you reinstall the game you’ll lose your boosters, therefore we suggest not to collect to many boosters on your game and it goes to the charges as well.
A Warm Welcome to the Candy Friends section of our friendly King Community
May I know which game you are talking about? As per my knowledge, there is no "Glass Ball" in Candy Friends Saga. If you can post back with the game name, the King team can move this thread to that suitable section.
Another Question -- before logging into the game through Facebook, did you delete and re-install the App? If you did reinstall the game, you will loose all the stored up boosters, like my friend @mysticalmysty mentioned. If that is not the case, please let us know and give us more details.
