So, this bug has been here for a while now. I have come to the conclusion no one is doing anything about it so here I am. This bug is where you will see that the textures of many old double-blocked items are messed up, such as beds and doors of all types. I honestly think you might have accidentally placed the texture boxes backwards for these items, so you should mess around with the textures of these old double-blocked objects until they look the same again, or at least to where we can't notice it.
