So the sigil books at the fest are 8 length x 6 width x 2 height and are 50 stones. I am supposed to carry 15 of those?! The 50 Sigil books from the Keep are 3 length x 3 width x 1 height
I know there was a bug with the original sigilbooks. IS this the same issue?
While some of these went out a bit bigger than intended, all sigil books magically shrink themselves the first time you interact with them. Reading the table of contents will make sure things are sized appropriately.
