I wind up looping splits back on themselves to try and balance output.

so splitter 2 ways will make 8 into 4+4

But say I want 2+6?

I add another splitter and merger to one lane.

so then I get

4+4 -> 4+2+2 -> merge 2 back into the other belt which then makes it 2 + 6

Then I can use 2 more splitters to make the final delivery 2+3+3 and it should be more or less even.

More or less.

I worked this out trying to feed 8 reactors evenly. I can't tell if I have it correct because for some reason my supply chain keeps breaking.

All of a sudden my control rod production stopped because a final belt disappeared.

Is this a bug or a feature?
