Are you sure you're not trying to use them as Monthly rituals? AFAIK, item rituals never worked as monthly rituals.

Ok, correcting myself:
Clicking on commander's orders, there's a new order 'cast item spell', that works fine. It was when shift-C:ing (ie bringing the usual cast ritual selection), scrolling on the bottom of the list, finding the notation 'item spells' and trying to click that one, that got me the error message I had. (Hopefully that makes some sense)

Now if I only had realized that yesterday... My bad. Anyway, shouldn't the item spells either work from ritual selection or the notation be removed from there?

That's what you get when you become enslaved to the quick-keys.
