BVT10

Hello, I'm having a problem with the stage 6 of the Cobra. If I assemble the exhausts according to the positions described in red in picture 3 (page 27), I don't get the same result as in the final picture (page 28), and it does not match with the left exhausts either. But if I move the digits a quarter turn clockwise, then the result looks correct. Does anybody else has noticed this problem?
