I was trying out Disguise Self & Alter Self and found that they cannot be crafted onto items.
I traced this down to both targeting restrictions (cannot target scroll/wand/potion in inventory), and to the des_crft_spells.2da where the item properties were not returned correctly, and the flags were set to disallow crafting scroll/wand/potion for the sub radial items.
I'm wondering if this was a deliberate choice to make these spells un-craftable, or if it was an oversight and was thought that if the master was set, then the sub choices didn’t need to be?
If it was not intentional, I would submit it as a bug fix one I validate the changes.
