The one thing I can't figure out, having just started the game, is the freakin relation between the sea chart and the treasure maps you get. How do I tell what each map corresponds to? Have I just not been to the areas they are showing? I have 3 maps so far, and none of them look like areas I've been to.

Ok, I just picked up the game and I've only played it for a day or two, but I'm sure that I read somewhere that you have to feed fish in the ocean, and they'll fill in your sea chart with the islands. Then when you look at the treasure maps you can see where they would fit. Not sure though, work's been getting in the way
