Question UK print of Discworld - Colour of Magic

[Cronos]

This is about the UK release of the 1st discworld novel...

I was wondering if anybody knew whether the publishers removed a printing of the book a few years ago from the shelves due to a printing error.

I only noticed recently after flicking though my copy that there is a major printing error, roughly after page 190 it repeats from about page 50 to 95, then continuing from roughly 240 to the end of the book......

ive thought of e-mailing the publisher but cant find a site or address for them

Im very interested in this and any help would be greatly appreciated
