Absolutely useless feature and should be removed. You should tell if you introduce such stupid things where you can loose several helpful items when trying to accomplish task for nothing?!?!?
I just don't get this. There was a event saying something like collect 12 crowns from next 16 levels to accomplish... Now as I succesfully accomplished this task I was told to collect golden crown from the map. Yes, I can see the crown but then what? Clicking it does nothing so is there a reward to be collected?
