We are really not understanding the setup rules for the World War scenario. It says to draw three continents and then add the tokens to the junction between the problem continent and it. But what if the cards are across the world from each other? We wound up with one token actually adjacent to the problem continent, which was easily removed.
I think we need to rework the World War. It's intended to block three routes, but not necessarily three on the problem continent. The way it is now, if it's anything but Africa, you can go around the continent at the same cost of going through the continent. With all three blocking that one location, it's not too much of a detriment.
Here's the description reworded, with an image to show it.
After drawing the problem continent, place the 3 War Tokens on the first 3 connections that are formed. Starting with the token #3 and going down to token #1. If multiple connections are formed at the same time, start placing connections at the top left of the newly placed card and go clockwise.
NOTE: All War Tokens touching the problem continent must be removed before the Problem can be solved.
Here's the example: The numbers on the continents are the order they came out, and so are the numbers on the tokens.
Say Antartica was picked first, then Africa, so the route from Ant - to Africa receives the first token. Then North America is picked, so Africa to North America gets the second. And finally Europe was picked, so North America to Europe gets the third.
This messes with two continents, North America and Antartica.
And then here it is when things don't go as smoothly with the initial card draw and the connections matching up.
