I've notice that there are 2 of the new mission cards that do not have the Vader Icon on them. Both are Subversion cards, 1 each for the Rebels and Imperials. Is anyone else seeing this and why do you suppose they are missing the Icon? Are they to be added to the base game set of missions if you don't want to use the "Rise of the Empire" mission cards?

Yes, that's exactly why they are for. So you can have 1 Subversion card regardless if you play with the Rise of the Empire missions or the core missions
