Thank you for making this mod - I am having a fantastic time with it. I really like the build-everything-from-nothing nature of the SeaBlock idea, but wanted Pyanodon's complexity. I haven't got too far yet since I keep restarting to try different factory designs, but just wanted to let you know the work is appreciated.
For my game, I decided to tweak the quenching tower recipe to give 5 copper/15 iron instead of 10 of each. Otherwise, I just seem to have endless copper sinks (or endless hand-crafted circuit boards to try to consume it all).
