I placed a reactor, heat exchanger and heavy turbines (vertically). The vertical positioning of the turbine graphic is too low, leaving a gap between the turbine and input pipe. After heating the reactor with the cube enough to heat the exchanger and generate some steam, the turbine graphics start dancing up and down.
I would not expect the turbine graphics to move.
Some other mods are installed, but according to the game (and my understanding of what they do) Ultracube is the only one to affect the turbine.
