I just used 2 consecutive coconut wheel upgrades on level 1604, which is a 31 move level, and I received no additional coconut wheels throughout either of the 2 levels. I think that this is garbage, and why would I buy anymore of these upgrades when they don't even work, and you always get penalized and get worse candy pieces whenever you upgrade?? I think this is very unfair, I try to save the upgrades for levels that they would come in useful for, and then to not get any additional upgrade pieces is a joke. What are the odds of playing 2 consecutive 31 move levels and not receive an additional upgrade on either one?? Pretty good if you're playing a King game.
