it's not falling apart, spine and such are fine...and from the looks of things, my copy may be a unique problem...no one else has made mention of this issue.

as loathe as I am to say it, but looking online for a +++

personally (especially considering this money I am spending here would normally have gone into the new models/'dex that released...and I am non-plussed by models right now) I have no reservations on this expenditure.
the models to support it can be used in any SM/CSM army as well so, while more expensive, they are no waste of my time!!!(and unnecessary to purchase, but fleshing out something I've already been working on)
