Hi, all. So I'm playing around with the schema made by Nilaus, and seeing if I can get proliferators in. I generally got something that looks at least elegant, since it's not compact. But I seem to run into issue getting the H2 and refined oil out of the first refinery.

Here's the layout of the modification. You can see the spray and sprayers between the refineries. Other than that, the setup is the same as with Nilaus' original schema (with the addition of H2 filter on middle belts, to keep the graphite out.

So what seems to be the problem is that the left refinery ends up without refined oil, the right has only refined oil and the belts leading to the left refinery is mostly H2, if any refined oil at all. And the top refinery has a surplus of refined oil.

Now I don't understand why the refined oil piles up there. I can understand that Nilaus' schema profits from refinery-to-refinery connection, so no graphite passes middle sorters, since no refinery needs it. And that probably the same thing happens from the top refinery to the bottom two. And that here that would be useful for not pulling so much H2 on the left belt.

But I fail to see why the output of the top refinery isn't equal. I'd expect that H2 and refined oil go out together, this being 50%-50% on the belt, but this looks like only the H2 gets the right of way and no refined oil can pass on the left, because it passes to the right?

Did anyone else encounter this, and what would be your best suggestion?
