This isn't about 'bothering' the author about just one dud book, and gambling on a one time/one book botch up occurrence,
it may have happened to others, and still be going on, without everyone in the supply chain being aware.
And besides, what author is that 'busy' when their rep, pocket, and customer product confidence may be at risk?
If it was my book on offer getting Frankenbound this way, I'd be very unbothered to be advised asap/yesterday
