Fulgora's oil oceans seem easy to exploit to get infinite resources, especially once you get access to foundation. While superficially this seems like a balance problem, I think this is somewhat counterbalanced by the fact that no yuoki ore exists on this planet, so any machines you begin with would need to be transported in.
Simultaneously, an easy way to limit the exploitability of the oil recycling recomposer recipe would be to add a waste product to it, something like green and blue dust? This way it's possible to reduce the waste products into fine dust and then compress it into Unicomp, but also the overhead of heavy oil unicomp farming on fulgora would be drastically increased. At the same time, any recycling of heavy oil on other planets would have no issues just eating their own waste products.

This should enable people who somehow start on fulgora to access yuoki tech, and would remove the need to ship in new tech from a spaceship, in addition to making the heavy oil recycling look less ideal for farming.

(it could be anything though, like ice even)
