448 Going to try out Create: Above and Beyond, since I lost a week of work on Retro SSP Insanity, due to a bug that deleted a bunch of the world. I had a backup from a week ago, but that means I lost all the bee breeding progress, and I can't just cheat that back with NEI, have to do it manually.
455. Last night I got the machine set up for making electron tubes from rose quartz, and adding those electron tubes to mechanisms to make intricate mechanisms! Didn't quite manage to get the bit set up to turn quartz into rose quartz, or the bit for growing crystals from seeds.
