Hey, Bama. You might remember me and my suggestion, but there's a big issue. All I have is Toomanyitems, Optifine and MCA for 1.8(including the core), and I asked my child to mine. But he just kept making mines within the mine, so I stopped him. I made him start again, but guess what? He just kept making more mines. Here's the problem in this picture.
Thanks again, gyser8
