My interpretation of the latest DevBlog https://anno-union.com/devblog-new-world-expansion-and-new-islands/: (https://anno-union.com/devblog-new-world-expansion-and-new-islands) is that you will see new islands in the New World if you use a previous save game. However, you might get a better mix of islands if you start a new game.

OK Thanks

If I have a saved game from dlc 11 and dlc 12 New World Rising comes, will I have access to the new islands in the new world and to Manola Island as well as all the content of this dlc? Will I have to start the whole game over and select all dlcs at the beginning?
