I had two clocks. Before I got the 1.1.3 update everything was fine. After the update I got the clocks to put one in the item frame, and the other one to keep. I held it and the texture was a bunch of multicolored pixels. I put it in the item frame and it still looked weird. It looks normal in a chest or in my inventory. I got off of Minecraft without leaving the game so I could do something. I went back on Minecraft and I was still on my world. The texture of the clock changed. It was still multicolored pixels but in a different pattern. I got off of Minecraft again and came back and the texture still changed, looking even more messed up. It looked normal for my friend who was playing with me because she couldn't get the 1.1.3 update with new nether blocks and stuff. When I thew out the nether blocks it was all missing textures that looked like dirt blocks for her, but I could see it perfectly fine.
