Win streak boosters can result in the automatic failing of various levels.

An example of a level you can fail instantly with boosters is 9591.

Notice that the only moves are the yellow candies, but if you were to start a level with boosters and win streak adds its own boosters, the result is that the game may not see any available switches, and because shuffle doesn't move special candies around, the result is an "OOPS" and automatic failing of a level. This happened to me because I had started this level with a timed color bomb and wrapped+stripe booster, and then win streak added its boosters. The result was that the color bombs replaced a yellow candy, and the rest with wrapped or striped. The game saw no moves and instantly failed the level.

I know for some levels, the starting candies are "protected" from having boosters replace them and are instead placed above the level. An example is level 9000. Any starting boosters you start with, appear outside the board and will drop in once you make a match. Can someone please review levels and make sure starting boosters/win streak boosters don't cause instant failures? Thanks.
