Hi Deidre, where are you playing the game - mobile or computer? If you are using a mobile device then all lives and boosters are saved just to that device so that you can play the game offline. For that reason, any crash or updating of the operating system or even if you uninstall and reinstall the game, you will lose all lives and boosters.
