"Avellone Novel (COMING SOON)" is not true. If it hasn't been made available by now, this item will not be coming to GOG. The description of items included should be corrected. At the very least correct the file list in Galaxy as an error is reported because this file can not be downloaded.

Originally I had the Wasteland 2 Director's Cut Digital Classic Edition. I bought the Digital Deluxe edition upgrade...And where can I find the "Novella 1+2+3"? Just the "Novella BOOK 1+2+3" downloadable. Why I didn't get? Are they the same? If not how possible to get it?

The list of included items on the product page simply seems to be mistaken. Outside of GOG, I am unable to locate any mention of an additional three novellas; so, I would understand each redundant instance of 'Wasteland Novella' to be the same as the equivalent 'Wasteland Novella Book'.

I had upgraded to the Deluxe Edition, as well. However, taking the upgrade path entitles owners to the exact same extra content as owners of non-upgrade version of the Deluxe Edition (even if said version is not marked as [Owned] or [In Library]).
