This is by no means an urgent bug, but I thought I'd let you know anyway. I planted a lamp post in the bottom right-hand corner of the attached screenshot. The light is there, but for some reason the lamp post itself isn't being rendered.
I have seen a bug where light sources remain even after an item is gone. It's possible the lamp isn't actually there anymore and the light from it has just stuck around. Obviously still a bug either way.
