I'm not sure if anyone can help me, but I'm doing a quest in the Caribbean section of the game where I'm supposed to explore other islands. I've leveled up my ship to the max and I've visited all the islands, but it's still stuck on the same quest even though there is nothing left for me to do. Help?

If you've completed the main story in the world, collected all lucky emblems, treasures etc, then that's the default directive it will give you when you visit the world, so there shouldn't be anything left for you to do there. 

Yeah, it's just the generic "You're done with this world but you might have missed a treasure chest or two. Smell the roses while you're at it." quest.

If you finished it after Big Hero 6, than that means a special event will occur after you leave the world if it hasn't already. Confused me my first playthrough.
