Enjoyed the demo.
I had the issue with the outreach center really really hating any kind of loop back into itself even when the loop was huge.
Had a different issue with things like dirty trash where a process building has an 'overflow' output and looping the overflow back to the input side with a merger. Buildings appear to have finite storage but infinite transfer capacity and this causes a behavior where the building sees an input rate of material of thousands of KiloGrams per hour and so it tries to draw thousands of KiloWatts per hour to the single machine which creates cascading weirdness with other machines on the same grid being starved of power.
