0.154.1 broke rendering of edge of the world
The edge of the world used to end in what looked like water going over the edge. Since 0.154.1 the water going over the edge is missing and even water leading up to that is missing, sort of. The water is still drawn if there is something behind it, as can be seen in the attached screenshot. The pier in the picture extends to a few dozen meters from the actual edge. About half of the visible world tree should be obscured by water.
