OK. So a while ago, I made my first Minium Stone and began playing around with it. Everything I tried worked fine. I set up an enderman spawner for the purpose of farming enderpearls to turn into iron. I got the setup working, and it all worked perfectly well (I was using the automatic crafting table mk. II). I then decided that I needed to move the setup to a different place in my base, so I dismantled it. When I set it back up, the recipe of one enderpearl and the Minium Stone no longer worked! I tried re-logging and all that, of course, but nothing was fixed. I tried making new minium stones, but that didn't work either. Further experimentation has lead me to believe that all of the transmutations to more valuable stuff (iron to gold, iron to enderpearls, gold to diamonds...) work, but the transmutation to less valuable stuff (diamond to gold, gold to iron, enderpearls to iron...) no longer work. I am at a loss... any help?
Oh, it might also be pertinent that this is in a singleplayer world with the Ultimate pack.
I have no idea whether I'm just being a noob, or if this is a bug, or what... but I couldn't find anyone else talking about it...
Thanks a lot!
