17839 appears to be impossible without spending a lot of gold, which I can no longer win in the chocolate box. If this is their way of pushing me out of the game, they are succeeding.
So sad to see Candy Royale is back. Thought they did a survey and everyone hates it. Eliminating the gold reward fron the chocolate box is just about the final straw for me. Obviously, they are trying to force people to spend real money on the game, which I won't do.
Same thing here. I read that you would still get the 40 gold even though it wasn't showing, but I just completed 27 levels (!) to finish the chocolate box, and I got zero gold. Agree this feature is what keeps me playing.
