I am deep into the builder tree for pragmatic and have the:

- all starbases start with an additional construction module

- all ship construction modules give 2 points instead of one

I had not unlocked mining barracks yet and established a number of mining starbases by just selecting the mining ring.  I setup the mining rings and then ejected the constructor to go about their business.  

The miining starbases showed one additional Stationed Constructor which should be correct due to the pragmatic ability.  

I expected that once I unlocked the mining barracks the starbase would use that 'stationed constructor point' to build the mining barracks since I have the starbase to automatically order upgrades.  However, it does nothing.  It does not use the 'Stationed Constructor' point, nor does it order up another constructor.  So again, in this scenario I no longer had a constructor at the base, but the starbase did recognize I had another point to spend on that base due the pragmatic ability that establishing a base gives two points.  It just did not do anything with the stationed point though there was an upgrade available to build.
