Runewars revised edition

I just boght the revised edition.
Me and one friend started a two player game.
I ended up drawing quest card 1B and 2B and he 1C and6B during game board setup(page 8 point 1 & 2).

The gamboard 1B and 1C is the same board piece.
Does this mean thet our game map start with only three game board pieces or should one of us redraw quest cards until we get ones that correspond to four different game board pieces?

When you're drawing cards to determine which boards to use, you're only supposed to use the ones labeled as "Setup Quest." If you look at the deck, the only cards labeled "Setup Quest" are the ones with the letter A, so you can't draw the same board twice.
