Steps:
I got a new SCH only weapon and tried to glamour it to look like the Grimoire Wing. I have done this with many other SCH weapons in the past, but it no longer works. I then tried glamouring other SCH only weapons with other general ACN weapons and none of them worked either. It seems that since SCH and ACN/SNM weapons are now separate sub-categories, SCH only weapons can no longer be glamoured to look like ACN/SMN/SCH weapons, despite SCHs being able to equip and use them.

(I really hope this isn't intentional. I will be incredibly sad if it turns out this is permanent.)
