I have had great time playing this game with my 5 year old son and he is incredibly able to play and understand. However this game has a few bugs related to achievements. In Raiders hub I dont get the first blue brick mentioned in the guide and I cant get fire to melt the snowman to get the last character so that hub is stuck at 94% for me. Are there any ideas about this other than a full replay of the game (good game but actually not good enough to replay) ??
