The following bug is a minor one as it is not related to functionality, but more so relating to texture. The normal function of smoke coming up from the fireplace should block any view behind the smoke. In the attachment provided, the smoke is blocking the view of all blocks behind it, including some leaves in the background, but not the water. The water as you can see is clearly visible despite being behind the smoke.

Make the water behind the smoke invisible to the player to keep consistency and realism.
