How do I separate/uncombine editions?

[Morbus]

G'day. I've searched for the above terms in the Manual as well as the Discussion groups and I am unable to find the answer to SEPARATING OR UNCOMBINING editions that should not be combined.

In this particular case - they're two entirely different books:

As evidenced here:

(Note: the above links are for the ebooks, but that's only because that's the only reference I could find - the books in question are entirely separate physical products too.) I suspect that the initial problem occurred because Amazon has the wrong product information for "Extreme Paranoia" too:

http://www.amazon.com/Paranoia-Extrem...

The cover image shows Paranoia XP, but the "Look Inside" shows "Paranoia Extreme". I own both books - one is the core rulebook, one is a supplement. They're not editions of the same book.

How can I get them separated?

You separate books on the Combine books page.

At the side of each book is a separate link - click that

Oh wow, that's confusing. Got it. Thanks!
