I've finished Library of New World Myths, but the other 3 maps remain locked. How do I get the Road to El Dorado map to unlock? Thanks!
pixel_player84134585 did you finish the task of the Library?
pixel_player84134585 You must have forgotten to talk to Ernesto after you collected the clues according to quest details. The next one should probably unlock after talking to him.
You can find quest details here: http://diggysguide.com/new-world/library-of-new-world-myths
or here: https://wiki.diggysadventure.com/index.php?title=NW_(Quests). If you ever get stuck with nothing new, make sure you've followed all quest items for the previous mine.
