Two specific ones:
Whisper’s Mantle (Order of Whispers light armor shoulders) – Went to the vendor and bought the 5 other peices fine, but shoulders were not even listed by said vendor. She had all 6 for heavy and medium. When to the wardrobe tab in the bank and searched Whisper under the light armor sub-category and the empty slot does not exist either.
Rogue mask – Bought it a few times with karma from the vendor in south western Diessa and it didn’t unlock. Bought a few more from the WvW armorsmith with badges an no luck either. Tooltip for it seems “incomplete?”, there is however a slot for this in the wardrobe.
Thanks for reading, hope it helps.
