| forgive me but what was wrong with it in the first place |
Most parts have a base size amount, plus a certain % of the hull's total capacity added to that. Since miniturization makes hulls bigger, it made those parts (which is most of them) bigger as well. Meaning whenever you researched a new level of miniturization tech, any given part had about a 1 in 3 chance of getting bigger, causing the net increase in space to be less than it should.
If you made a design with lots of the same component (say, a sensor barge), this effect was so prnounced that researching a new level of miniturisation could actually cause a buildable design to become unbuildable, because the multiple sensors, etc, all grew in size at the same time and completely overtook the gain in hull size.
Now though, or at least, when 1.3 beta3 comes out, all parts will stay the same size and will only vary based on which type of hull you put them on. Miniturization will not affect them at all, aside from letting you put even more of them on your ships than before (since now you'll actually gain 10%, 15%, etc, instead of losing half or more of the new bonus because the parts grew at the same time).
