Accidentally hand-placed the charged (non-dormant) cube in the output of a boiler instead of the input, and get a repeating error: "Cannot find the ultradense cube" and "control routines failed". It does stop when the cube is taken back out of the boiler.
Reporting since the mod does seem to lose track of the cube (the explosions stop, etc), and I'm unsure if this results in long-term crashes/bugs with the control routines.
