Was that all you ordered not the printed version?
I don't remember there being a tier that included the digital copy and NOT a printed copy. By 'digital version of the book' I assume he means the PDF dated November 2017 that we recently got from the project creator. Interestingly, the PDF is dated the same month as one of his updates saying they were in the middle of printing and almost ready to deliver...
I was kind of insulted by it, because we've been asking for it for months, yet he kept holding it without explaining why, then he finally gives in but sends us an old one. We could've had this content since November and found any and all errors for him so he didn't have to deal the errors at PRINT time. He likes to make unusual decisions and not explain them so we can only speculate why he's doing things this way.
Oh, and he said he'd be back in a few days to update us and it's been over two weeks without a word.
