I'm curious which version to be using at this point, since Dark's got deprecated and the original version was updated. I'm assuming you are intending to revert to the original, but the recipes are not entirely setup properly for it. Just from a few things I've noticed:
-Circuit Substrate Tier 1 used to require a lengthy process with the green algae, but now is switched to using Stone Brick -> Stone Tablet -> Fiberboard (??)
-Flasks require Iron Plates instead of Glass
-Clay Bricks are uncraftable, as they are looking for Angel's Clay instead of Py's Clay
There's probably more, but yeah
Also, are you planning on incorporating Py AL and Raw Ores at some point or is that never being added to this modpack?
