While looking at the campfire smoke behind a body of water, the smoke does not cover the water as it does with the surrounding objects. This creates a weird overlay making it seem that the smoke is behind the water. I tired this with lava also but the graphics error did not happen. In fact the lava registered as the water should, not being able to see through the smoke. As far as I can tell, you can set up the campfire and look through the smoke at any body of water with the same outcome(graphics glitch). This isn't a high priority, it's just mildly irritating.
