This level requires you to eliminate 100%of the items. I usually save balloons on the board for when I need them, but right before I can, the game keeps knocking a block off the top and telling me I failed the level, even though there's a balloon sitting right there on one of the blocks. This happened to me before on another level and I thought it was because the boosters were sent from friends when I asked for help. But this time the balloons are part of the original board and it's still happening. How can I fix this?
