I have been stuck on a level for several days (unusual for me) and after using all of my boosters I finally beat the level only to have it just shut down while it was posting my score. My tablet just went back to the home page. When I opened the game I hadn't passed the level but all of my boosters were gone. This has happened several times lately, in all of the King games. I'm tired of losing my levels and boosters. I'm ready to uninstall all of them.
