There must have been a moment at the beginning, where we could have said no. Somehow we missed it. Well, we'll know better next time.
I got the third edition of Hansa Teutonica by Argentum Verlag and I think it is missing the pawn used in the 2-player game.
How does this pawn looks like or this componente really don't exist?
As Tall Walt said.
Just to add: you are not missing anything as far as gameplay - the pawn-2-player variant in the first printing was widely regarded as not very good (broken even?). The new 2-player variant, that doesn't use the pawn, actually works pretty well!
