Power Station not Forming

In the GT New Horizons pack, latest build. Also tried updating GT++ to 1.7.02.24 with no change.
Power Station checks structure, gives no error message, but complete.

Expected Behavior

The Multiblock should complete, or give an error as to why it can't.

Current Behavior

The following messages appear when the controller is placed in an otherwise completed structure:
[B#402] [21:13:31] [Client thread/INFO] [GT++]: Creating Tile Entity with Meta of 2
[B#402] [21:13:31] [Server thread/INFO] [GT++]: Creating Tile Entity with Meta of 2
[B#402] [21:13:33] [Server thread/INFO] [GT++]: Checking structure for Industrial Power Sub-Station.
[B#402] [21:13:33] [Server thread/INFO] [GT++]: Checking structure for Industrial Power Sub-Station.

The Waila Tip doesn't change to indicate the structure is complete, and no maintenance can be done.

Possible Solution

I can get an error message if I use an over-tiered Dynamo Hatch, so it gets that far, but it might not ever leave that loop.

Portable Scanner reports a higher tier Max IN than I have Dynamo, and 0 Max OUT. Probably uses is also 0, though I don't know if that's actually useful.

Steps to Reproduce (for bugs)

Build a power station (27 cells)

Context

I would like to use it.
