Letherfoot Raider Skullcap - LORE Message?

[Loftus]

Hi all -

Just completed subject quest for item to insta-TP to WC. Have one, traded to friend.

Friend tried to trade back to me on one of my different characters but trade failed due to "LORE" message.

I meticulously checked my bank and inventory for anything remotely similar and I don't have a Leatherfoot Raider Skullcap in target character inventory.

Is my UI possibly hiding some bank slots? Anyone have suggestion?

Please help!
