I'm trying to build a 7x7x7 reactor, but "Casing incomplete" is always showed in the fission controller.

Reactor:
reactor.json.txt

All the 294 Fission Reactor Casing are corretly placed. No edges.
Also all the coolers are well-placed.

I tried building it first with the building gadget, then by hand. Nothing to do :(

Solved: The Fission Controller was placed on the wrong side
