I've noticed items embedded with 1917 (old zealot) appear to have some null data in verses 3 and 4 of their loresong. They don't show the activator verb, whether the item is rechargable/empowerable, and the number of charges. Since 1900 seems to be a discard-list, maybe this data was never filled in?

This was probably answered already, but what happens when someone runs 1617 and 1917 together?
