Shoot an email to either Pearl Games (info @ pearlgames.be) or Z-Man (csr @ zmangames.com) explaining the situation and see what they have to say.
Upon our first full game I discovered one of the red dice has an extra on it and no two.
And the six could pass as a seven, as well, with the start of a pip in the middle giving it an almost H look.
Was this common?
It's not a big deal. I'll just fill in the extra pip with marker.
