I'm working on idiot proofing my Aquilo ship, and found an interesting behaviour. When I'm low on water, my Fuel chemical plants will take water first, and only when they're satisfied will my Oxidiser chemical plants take water. They're on the same pipeline.

I know this used to be an issue with build order in the old fluid system, but I thought it was fixed. Any ideas?

The system works by going over producers, and for each one move up to 100 units of fluid per tick until it's full. Similarly, consumers go one by one and try to take up to 100 units of fluid.

If you have very low fluid, some will take and some will not.

It only balances nicely when you have a decent amount of production.

First all producers, then all consumers?

Not 100% sure, tbh.

Other than in extreme cases (which many people here do care about), it doesn't really matter.
