I doubt whether that bothers many now that it is so difficult to get it up one level in the 1st place, when all of those boosters are available from choc box.
I think more are upset that you can no longer build or use it on lower levels. Phooey
Ya I hate when you lose them as ll at once but takes passing a game to earn one at a time but now only in new levels and lose a game and they all disappeare, that's shitty, not fun
