I love playing this game. BUT my massive issue is, I cannot seem to unlock the tropical artifact and I'm almost to end of the Volcanic Islands. Please help. My snow artifact is at level 3 aswell. Why can't I unlock the tropical artifact?

Love the app. Stories are good although some of writing could be better. Should always be proof read!

I absolutely love this game. I have however missed out on getting shea and just wondered if there would be another opportunity to get her again.
