Oni Blighted Cosmetic Bug (PC)
Platform: Steam (PC)
When equipping the Shattered Spike from the Hallowed Blight Collection onto Oni with any other body cosmetic, this will cause the Oni's head to glitch through the front of the mask, causing the mask itself to not be visible when in-game.
This only happens when you enter a match, and the bug does not appear when in the killer selection screen, the item shop, or in the starting lobby.
I have played around 10 matches with different body cosmetics and mask cosmetics for the Oni, and the Shattered Spike mask is the only mask that creates this bug.
I'm not sure if this only affects the PC version.
