When I try to use a booster (have lost 1 stripe and package candy and 3 fish so far) in Level 984 an error message comes up, the game freezes, I lose that life and any gifts of life sitting there.
I think the game is obviously registering that you have clicked to use them. Can you let us know what the error message says, maybe then we can recommend what to do to try and help. Maybe post a picture here if you can.
