An item that salvages into nothing
Similar to some of the level-up weapon rewards that might salvage into essence(s) of luck, but never yields mats. Since Hearthfriend is a randomly dropped “leveling weapon” I’d guess it falls into the same category, meaning your result is probably not a bug, but an unusual artifact of design.
I dont think you can mystic forge them either.
The leveling weapons can’t be sold or mystic forged, and attempts to salvage them produce no materials. They’re basically useless once the character has better items. I usually just end up deleting them since they are pointless for level 80s with ascended gear.
