The ScienceCostTweaker mod overhauls the science costs (with angels/bobs things added in) and this mod is overriding those recipes with more simple vanilla'ish ones (with an extra thing) in comparison to its more complex variants. Even with the override disabled it is still adding an element that doesn't quite fit with the style of SCT (although that could be changed slightly work well). Though since the tech component packs are basically just duplicating the costs in SCT for science packs it would be awesome to get a setting to disable their existence altogether or perhaps an option to reduce the cost to fit SCT better (so it only increases it to the normal BobExtended amount instead of increasing it a lot). :-)
