Looking at the image recently added in BGG of the "Final Map," I spotted a typo.
See the box toward the bottom of the map illustrating the various routes on the map. Below those route images is text noting that land and naval units need a base when exiting. The text for Naval units reads:
"Route with [image of naval unit] requires a base when exiting with a naval a unit."
Strike the second "a" between "naval" and "unit."
Thanks, being fixed.
