The Forgotten is the latest official character unlocked in the most recent booster pack (supposedly the last booster pack)
I have the character unlocked and can provide the save if needed, I just need to know where to send it
There is an attach file area under the text area, you ZIP it and click the paperclip icon, then you add where in what file location it needs to be placed in the text part so it can be access in game by Cal along with any other pertinent instructions.
