Notebooks Retrieved From Bookshelves Unreadable

[Batrachophrenoboocosmomachia]

Expected behavior:
Retrieving a stored Notebook from a Bookshelf creates a usable Notebook with its original contents.

Current Behavior:
Retrieving a stored Notebook from a Bookshelf creates a non-usable default Book item with the original name/description and no 'Unique Power Self Only' property to read it with. Fortunately no information appears to be lost, just the ability to use the retrieved item itself (see below).

This can currently be remediated by taking the 'default-ified' Notebook to a Printing Press to copy. A newly-created copy of a bugged Notebook will be a normal, usable Notebook with all the original's contents still inside. EDIT: Not tested yet, but I suspect placing it inside a Book Bag and retrieving it will also fix it.

Placing a 'default-ified' Notebook back into a Bookshelf will make its contents readable.
