I lost my "Catalog of Shields" after the forge was fixed. Any chance your item disappeared then as well?
Hmmm, now that you mention it I logged in the other day and only saw my 3 working with stock books (people seem to be terribly careless with this book in particular, I find them often), that would mean that my Book of Blades was probably (hopefully) in 'mind' which would then mean that my Shield Catalogue is missing
And it now dawns on me I forgot to check my glyphs
