I thought it was my imagination at first, but the game keeps deciding my tier goals -- the ones where you collect multiples of the same item -- are complete way too early. The ones where you collect letters haven't had the problem, but the others are awful. For example, the diamond tier, stage 3, Volcano -- I had 29 of whatever it was I collecting, I think I needed 64 or something? and it suddenly awarded the Golden Banana.
