This is interesting. I was able to completely suppress the extraction economy of a HME body. However, this looks like a bug to me.
It is a 6+3 HME body without volcanism, without biologicals, but tidally locked. The port is a T3 ground port "Fruit of Countless Toils". Before, the body already had this port, three T2 agricultural settlements, and three agricultural installations. With the recent update the market was mixed, a complete mess, but with a shipyard with 33 ships. No grain, lots of steel and titan (weak links to distant refineries), and some minerals. Stuff.
Now, I added a fourth T2 agricultural settlement (one open slot left on the body now). The economy switched to now 1.2 agricultural without any additional economies. 260kT grain and 30kT natural fibers for sale. In the architect view, this T3 ground port shows four strong links to the T2 agricultural settlements, but no weak links to the three orbital agricultural settlements. No weak links at all...
The shipyard went from 33 ships (all but the alliance ships) to nonexistent.
