How important is it to have exactly 30 red discs? My copy from Essen only has 29. I haven't played the game yet but from what I can tell there's a special rule that kicks in when such discs run out, so perhaps it is important to use 30?
Do you think there's any value in contacting the publisher to notify them about the missing disc? I could probably find a substitute easily enough but is this the sort of info that publishers use in their QA analysis?
