When you place Wolfsbane Fangs on a weapon wall mount, it does not show up. See image.

Wolfsbane Fangs not visible on weapon mount

Same here, it doesnt show weaver daggers for me either. Xbox x console. 

None of the dual wield weapons display correctly on the display mounts. The mitey claws seem to be the worst in my game as they just float in the air near the display mount. A lot of weapons seem slightly off in their positioning. It’s cosmetic so likely not a priority fix, but hopefully it will be addressed.
