Love the game but how do get Volcano – Tiny Castle Review

I’m level nine in the game and have a bunch of creatures, and even got to the bridge. It usually allows you to explore to the skull cavern unlocking volcano magic and the Phoenix. But, it says “Complete Goal” instead of “unlock volcano”. I even deleted the game and it just saved everything. How do I fix this?
