Same thing here, the dark harvest collection is completely unfinishable at this moment….. Got the stealth gliding mastery, used it with my necro and it didn’t award me the gift of hidden descent trophy; later, I bought the Itzel funerary customs from the itzel vendor at the maguuma’s breach WP, and even though it shows up in my inventory, it wasn’t recognized by the collection tab. Really frustrated right now, hope the fix is in its way…
