So I'm assuming, due to a problem we had with a late-campaign haunt, that the family crest tokens were intended to be blank on one side? The ones in my box show the crest on both sides of the token, which presented a problem with our specific haunt as we were supposed to turn them over so that the crest was initially a mystery.
Yes. The crests were supposed to be one-sided and the error slipped through. The designers and writers have gone through the haunts and we believe all the haunts will work with the current tokens, although you lose some elements of surprise.
