[2021] SE: This is freakin' annoying. Trying to avoid using others' designs for arcospheres, but my patience is running thin.

I just treated it as a separate closed environment. I've put it into it's own logistic network, and then figured out very basic logic to determine when should it try to use which recipe, based on some min/max that it should try to keep. As others said, a display showing the current balance is insanely helpful.

Once some minimum in the logistic network, only then I allowed it to output that arcosphere to the main logistic network. That way I'd never get into a deadlock where it'd just run out of a type.
