Describe the bug
Building an Advanced Processing Array without any input buses and enabling distinct buses crashes the game with an index out of bounds exception and prevents the world from loading. Using MCEdit to delete the controller allows the world to load again.

Relevant part of the crash log:

Forge: 14.23.5.2859
GTCEu: 2.3.1-beta
_Modpack: Nomifactory CEu

Setup
Does this issue happen on Singleplayer, a Server, or both: Singleplayer, not tested in multiplayer
Does this issue happen on a newly generated world: Yes

Steps To Reproduce

1. Build an advanced processing array. Specifically I used an auto maintenance hatch, two ZPM input hatches, one ZPM output hatch, a ZPM energy hatch and a machine interface filled with 64 IV chemical reactors.
2. Once formed, open the interface and click distinct buses, the game immediately crashes.

Expected behavior
Not crashing

Also tested without wallsharing in fresh world.
