I try to build this multi block but i'm stuck with "Incomplete Structure."
I tried many combinations. I can't find what i missing. :/
This is what i test in creative mode :

ZPM Energy Hatch + Maintenance Hatch + ZPM Input bus + 3 ZPM Output bus + Controller and casing.

It requires 5 output Buses.

For whatever reason I've wrote the tooltip wrong. Fixed in next release, since it's only a typo I won't release a hotfix.
