What to do with the cursed city for the soulblight gravelords?

So I bought the cursed city box and the new deathrattle box as what I thought would be the beginnings of a great soulblight list

But when I opened the battletome I found out that all the names characters from cursed city aren't in it. The age of sigmar app hasn't updated so I'm really not sure if units like Rardukar are permanently out of the game or not.

Should I try and exchange the box? Im sure the board game is great but I feel a little miffed spending $250 us dollars on a squad of deathrattle skeletons
