To not clutter your main comment page ill just post feedback here. The complex crafting system unfortunately does not work to my experience. I tried creating an item that requires T2 copper + T4 Iron then combined with T4 copper + T3 Iron to create something that looks like a clock i believe. The problem is that there is some excess materials because the speed of refining low tier items with high tier causes a timing delay and then the merger tool gets fed another item that was not merged properly before. So for example I have a copper plate coming into my final combiner because its too fast for my Iron bolts. There isnt a way to sort these excess materials out of the crafting recipes so at best i was able to combine a single complex material before the whole crafting rig broke and i had to start over again.
