IoG Play Input Query

[Poor Yorek]

I noted tonight the first play input for Invasion of Germany. I am just curious regarding how old plays from the five expansions from which IoG was constituted will be carried over? I ask because the bounty points for plays and AARs in IoG seem predicated on zero plays/submissions rather than the, frequently, multiple plays from the previous expansions? If the Bounty Points are to mean anything, one shouldn't get a different (higher) award because of entering a play via IoG rather than in one of the original expansions.
