Not so much a critical bug but would be a really nice improvement to the bees. the bee hives look really nice on top of scaffolding, it makes them look like proper hives that you would see in real life but unfortunately the scaffolding stops the smoke from pacifying the bee hive above it so you have to hover the hives above the ground or hang them under an object which is not so realistic. Could you allow the smoke to penetrate the scaffolding block to allow us to place campfires under the ground to make bee farms? So the blocks in order from bottom to top would be campfire:grass:scaffolding:beehive and if you make that you will see what i mean

Also from testing it appears that smoke will penetrate through an oak slab to pacify a bee hive above the slab, so it makes sense that it should be able to pentrate through a scaffolding block
