Hi @RbinSparkles92, welcome to the community. You must be playing the game on a mobile device because that is usually where you might suddenly find all lives and boosters missing. They are saved just to that device so any game change or operating system update can cause you to lose everything except the gold bars. King cannot reimburse you for boosters that you gained from events but if any of them were purchased please let me know and I will have to direct you elsewhere.
