I played a challange for week to collect 250 gold bar and almost finished 500 plus lvl but suddenly that gold bar disappeared!! I played 25 hard level collecting 10-15k blue candies in each level to 25 lvl to get the 250 gold bar .. i feel so cheated!! I almost quit this game .. before 2018 i was a top candy player too .. i just came back to play in 2024 and i again fell cheated 😡😡
