The Loom block texture seems to be switched around. In particular, the top. I came down into my basement to find my loom apparently facing the wall, so I broke it and re-placed it. That's when I realized that the top face was pointing the wrong direction. Additionally, the bottom face is identical to the top face. (Also, I'm not sure if it's intentional, but the sides are the same texture as the back.
Thank you for your report!
