all the magic stf is tied to thaum research as captain_oats said.
I made the mistake of starting to use sapphires for lapotron crystals and realized I was going to use all of my preeecious shiny things, so I started going down the route of making a ton of ruby dust to make the energium, a ton of circuits, which made me realize I had no redstone left, so mined some more, made some more energium, mined some more, found some more ruby, danced for 5 minutes till I was out of ruby dust again, rinse repeat lol
Yeah... about that. I was JUST starting to feel that smug feeling that I had started down the path that I was 'beating' the game, since I was swimming in resources, etc. I heard the sound similar to an anvil falling on wile-e-coyote but ignored it. I started progressing through some quests after doing a few in space and went to mars, and decided to go back and finish some in fusion section. decided to see how interesting that assembly line was to make. Started making IV motors and making the block itself to make the book was interesting in itself, opened the book and as I read the layout/requirements and looked up all the info in NEI, that aforementioned anvil hit me smack on the noggin with a resounding NOPE meme.
btw, adv miner 2 on mars is an endless font of random stf. I've had mine running for like 2+ days now (real time) chunkloaded and all and have checked it twice to ensure it has mining pipes and it's only gone down 20 so far. Assuming it's cause of the increased Y level, more stf has a chance to spawn.
