Today I built my secont actively cooled Turbine/Reactor combination. The setup is the same as my first one. So the problem is, that the Exhaust Fluid Tank of the Turbine gets filled with steam from my reactor. I checked all the in- and outputs and compared them with my working one. Is this a known bug? How can I fix this? I'm not able to remove the steam out of this tank :/ edit: How I fixed it: I removed the complete multiblock struckture and rebuilt it. After that all worked as it should. After some research I figured out that this is a know bug.
