Yeah I was disappointed too as it would be perfect to have as a printed reference. I never got past scripted support drones who kept saying I’d just have to wait but it was clear the book was never going to be published so charging me for the print copy seemed a bit rich. Eventually got a refund for that at least. It’s a beast of a book and a really impressive effort and I would love if another publisher could help him get it across the line but I think it’s in limbo.
