In the bottom left corner of my base, I have 3 set ups for coal liquefaction. The top two are self-sustaining with their heavy oil. It always goes to the refinery first, and the cracking chem plant second. The bottom one is not self-sustaining, and requires constant heavy oil injections in order to continue running.

I fixed it by disassembling the heavy oil pipes, refinery and chem plant, then reassembling them in a different order. I had to place the refinery first, then hook up the heavy oil input, then the chem plant and its heavy oil input before it worked the same as the other two.

order-dependent behaviors are an annoying long term problem in factorio. thanks for such a solid example!

This may change one day but this is currently how it works due to how entities are updated in Factorio.

How are you getting the heavy oil drums into the assembly at the centre bottom?
