Same here, it's the only thing missing for 100%. I'm on Xbox Series X. Tried everything to fix it: reload, hard reset, fast travel, meditate.
@r6mick_uk you get the hood after you kill all the members of the order. So basically you have to beat the game to get the full set.
@ubi-baron I'm pretty sure it was directly after the 1.0.4 update. I had both (wolf & fox) and already completed the game. They just disappeared.
@ubi-smash I have the same issue. My quiver is fully upgraded, for my last rations pouch upgrade I'm missing 5 fabric (used it for the altar). Settlement is lvl6 and I looted 30-40 chests in high level areas without getting any fabric.
