I wonder where they are with the development. I am not a paid patron supporter, so I dont know. I can only see the reports from three months earlier. Hopefully they are almost done.
I'm not a paid supporter either, but based on what is visible, Chapter 7 is finished, but only the first half of Chapter 7 has been released to Patreon supporters, as of December. So I'm guessing that December through now have involved (in part or in full) either debugging Chapter 7, writing Chapter 8, or both.
