I am having a real issue with level 7639. It requires a key to unlock a set of blocks that need to be eliminated before you win the round. The final key does not drop until you have no moves left. I used 10 gold bars and kept eliminating the candy from the area where the key was supposed to drop and again it did not drop until I had no moves stupidly spent another 16 gold bars to try to get the key again. It was only after I used two hammers to knock candies out that a key finally dropped. I understand it’s supposed to be a challenge but not having these keys drop when all the other candies are eliminated is a real issue.
