However, i admit the Reactor should be slightly more expensive, eventually. Probably move it to Advanced Machines, thus requiring Carbon Plates and Additional Alloy to craft.
Oh great, tovarish' Dreamer, you did it...
No, I'm joking, this is really thing-that-you-should-do-with-Reactors.
BTW, what aboud snow and ice block cooling?
And (maybe already reported) I can remove Reactor with maximum 5 added Chambers (if right-click with Wrench at Reactor) and all will be fine, even Chambers will be dropped, but with 6 added Chambers it will only open GUI.
