I went ahead and re-added the item fields to this template. This is used in queries by the Item template. Basically, it allows an item page to look up which NPCs sell said item and displays them on the item page. Refine_Steel_Instructions is a good example of how this displays.
No need to force resaves on all NPC merchants and trainers. The site will eventually do that silently ater a couple days.
Thanks for catching and fixing this, Kindragon. After I finished the half-completed project of dropping the "Item: " prefix, I went about eradicating the prefixes inclusion in the templates.
I could not see how that particular change would create the problem, and simply went ahead with it. I'm glad you took the time to sort it out. Thanks a bunch. I think that function is pretty important to our item pages.
