I got the following LUA error when opening a Public Work Order for "S.A.V.I.O.R.":

It seems to be item specific - I can't craft this item but the error won't pop up with other ones I can't make.

Edit: it also pops up for Fierce Illimited Diamond but not Elemental Lariat (I can make neither).
No sign of it for any recipes I can craft, though I could only check with Treatises since work orders are extremely hard to find.
