I recently moved to the Progressive Era, but I advanced to the Progressive content map a few weeks ago. A bonus quest has just popped up after I completed the research requirement for the prior bonus quest. The new quest, "Gonzalez's Last Move", requires me to acquire El Fuego, which is on the Industrial Age continent map. Apparently I did not clear that map before I took ship to the Progressive Age map. Now the bonus quest is impossible because I can't reach the El Fuego province. Is there a way to clear it?
