Story Mode Islands glitch

I have been playing with my tribe for many hours and the ports always take me to islands that I have been before and I can never get to more difficult islands.

Which way have you been going on the ports? The only way to get to more difficult islands is by going north and if there are no northern ports, you should go right until you can go north. Ports that are on the right are islands of the same level, and ports on the left are easier islands.
