Hi @Dreuz95, just checked and you're already flagged for the content unlock.
Providing your DoubleID is still connected, you have the content already, as of the 24th June update with version 18.104.22.168. You do not receive a notification for this change, and the DLC will still show as available to buy in store, but the content is unlocked in your game.
When you have the base game only, you have 6 wardens. When you connect your DoubleID you get 2 free wardens. When the DLC is unlocked (as yours is flagged to), you receive 8 additional wardens as well as 8 new Plots and Prisons.
If you can see any of these warden options when you start a new game, then you already have the DLC content:
Hunter McGreevy, Rick Beresh, MD, Tom Dunwright, Warden W-800, Walt "The Wolf" Wilson, Shaun Fernandez, Nero, El Cocinero
If for some reason this still isn’t showing please let me know, however we have so far had no instances of missing DLC where a user’s account is flagged for the unlock, as yours is.
