i just tried 0.3.0, 0.3.1, and latest 0.3.2 builds. when you open the gui on the redstone port, check the icon next to the power icon, that controls rod insertion. the value of the 'off' input doesnt get saved when you commit. i was basically doing the same exact thing as the power on/off circuit, except 1 set to control rod insertion %, the other 2 emitting on different fuel temp levels in the core. wont work if you cant set that second percentage input. i put it up on the github issue tracker, shouldnt take long for him to fix that one
