Call of Duty: Black Ops 6 players aren't happy after discovering that a weapon blueprint for the PP-919 submachine gun is unusable when the equipped optic sight is removed. The Occult blueprint is featured in the Dark Practitioner bundle in both Call of Duty: Black Ops 6 and Warzone, and while it does come with an abundance of cosmetic items, one of the included blueprints appears to have a serious bug that would put the player at a massive disadvantage if used.
