Hello, I am not sure if this is a bug or not but while working through pottery I discovered that a couple of Recipe books which I have scribed are possibly missing the following recipes: "Elegant Charms" ID 37533 ID 37495 Elegant Charm of Mental Invention (Cloth) ID 37478 Elegant Charm of Physical Adaptation (Leather) ID 37486 Elegant Charm of Physical Invention (Cloth) "Simple Charms" ID 36694 ID 93180 Simple Charm of Physical Adaptation (Metal)
Pottery recipes, and yes those four recipes should be included in the list of scribed recipes provided by the books, but are not scribed.
And the 4 recipes DO count towards 350 as I tested this about a year and a half ago when I ran into the bug/issue. Arranged it so that if I succeeded the next unknown recipe that it would grant a skull up. I believe I made the Elegant Charm of Physical Adaptation and did get the skill up as expected.
