Unforgiven Legendary pistol is absent in part_name_mapping.json, so UserFriendlyName failed to be showed right in list. BL3(BOMwdWzeupH42PZLpfXV81Cch17TWnSUVnbNKQ5w2AqIkVzjFR7y) code for check. Item with that code was get "legaly" in game.

Some addition: there also another items with wrong naming.

Gunerang / Bangerang pair: frendly name Gunerang for both

BH41QAmTejiYPTns8/PsjemiZFkgtlDZtm1FX6unL6V+A1Y=	Gunerang	Balance_PS_TED_Bangerang

The Lob / Shocker pair: frendly name The Lob for both

So this is kinda an issue with how I have to determine item names. The title of a gun is mainly determined by the barrel (most cases), but because Gearbox is Gearbox, you've got unique guns (Lob/Shocker, Gunerang/Bangerang) which can share a barrel despite different balances. For now, until I feel a bit more energized with this, I think this is just enough of a niche case for me to not quite feel like fixing it.
