Okay, I see. Yeah, when I went back there later, it seemed to work fine.
While I am here though, maybe you guys can help me out with another issue that is far more vexing.
For some reason, I can no longer craft any ore blocks from the iron/copper/tin etc. essences that I have grown. It was working earlier this week, and when I played a few days ago, I could put them on the crafting table like before, but using either the 2x2 arrangement or a full 9 on the table doesn't work (I forgot which it was, so I tried both.) You can place them on the table just fine, but no ore blocks result from it ever since it started acting up.
