The Storage Cabinets list Deer Carcass twice. At first, it just seemed like a one-time glitch but it appears to be repeatable and consistent across cabinets. The number of items in the stack changes correctly in both stacks. I am not sure if the extra stack is actually claiming a slot, or if this is only a display error.
Cabinets also appear to be negatively impacted by inworld lag. There probably isn’t much to do about that, though.
