Weird, there's nothing there for me. There's just the coin count, and the character portraits under that.
maybe try re downloading it idk how else i can help
Still not there. I looked at their Patreon page and I see the book in some of the screenshots, so the only thing I can think of is that you've got a later build of the game than what's available here. The build here is from June 1, 2019.
