I just finished FIRST in the extra iceland, where you get the statue of Mother Nature. I got ten keys and decided to use THREE of them to open a chest and nothing happened. I did it a second time, meaning I used SIX keys, and it did it again. I lost Six keys and got nothing for it. I like the game but that made me upset as getting keys is difficult. Please fix the problem and I would like either the content of TWO big chests or my keys back.
