Thanks for setting up a fix for this. That's one harsh bug.

I'm going to give you the whole deck list for each character the best I can remember. I don't know if it's easier to do a massive replace for everything or do it individually, but the decks sure lost a lot of the special chapter cards. Very few of those stuck around for some reason and that caused a lot of rebuild, so it was just easier to give you the whole lists than try to identify what needed replacement.
