the game shuts down and looses all of my boosters, as well as the life used at that time.

I have complained about this issue before with no response or correction. I play using android on a nook hd+. Today I lost color bombs, fish, and hammers with the shut down. The hard levels are about impossible without boosters, and you should be able to restore lost boosters.
