Hi @PROUDCAGLEHEAD one person wrote about this on Oct 7th but never wrote back. The studio will not make a change in a level if only one or two players comment. What usually ends up happening is that some players come here and report a level but then the following day they write back on their message saying that they cleared it. So when the studio sees those second responses they feel that the level is doable. Since only that one person and now you are saying this, I don't think that King will make a change immediately. These higher levels require boosters now.
It's frustrating that it is now June 2019 and this problem hasn't been fixed. The mystery candies never appear. It's messed up that the expectation is to burn specials accumulated along the way or purchased (for those that spend money on the game) to beat a poorly designed or flawed level. Please fix the issue.
