1. Even though the craft queue thinks I meet all requirements the craft button does not work.

2. As shown this is not an issue of having not having the mats in the inventory or something

3. In this case the shopping list had me go buy a pvp reagent even though the patron orders always supply this

I dont know how you coded this but I would guess that the craft is failing because the craft queue is trying to craft with -my- supplied reagent but the patron order uses the patron's supplied reagent.
