I know there is an errata about the Greenland picture on the back page of the appendix, for certain rulebooks. All spaces to the left, below, and lower left need to be covered for each income space covered.
However, I think I just noticed another typo. The text about Greenland states, "Greenland features two "income diagonals," both providing silver each round. So you can get up to 9 silver each round from Greenland.)"
Shouldn't this be "up to 8 silver each round"?
