Each of the attached screen shots over the taken over about an hour show one of the new cod mobs that is refusing to drown. It sits next to a birch wood fence that is one block above water and sits like it is still swimming. What is even more odd is that when salmon that are in the same pool get caught on this lip, they drown in the air like they are suppose to do. This bug only effects cod and it is not always just one fish either. When other cod jump up there, the same thing happens.
