The "hard" part about the 1st puzzle is that the answer is behind a locked door. If you open the wrong door, you have to buy the key to understand what to do. And if you want to keep your gold to buy the other items, you can't win. It's not really hard, it's a bad design.
How does the math work?
I can cool a double nefastium cell (+23M heat) with 2 ultimate vent (-11.5M heat) but if I use a ultimate cooler (+5M) next to a ultimate heat outlet, the vent explode.
It says that the heat outlet send 5M per adjacent component to each component so the vent should have 5M heat whitch is less than the 11.5M the vent can remove.
And where is the heat management now? The heat exchanger used to balance the % of heat in each component and the reactor but the heat outlet and inlet have flat values.
Will do! For now I nerfed, but if keeps that way, I may remove entirely.
