[Bug?] Constructor Drones don't regenerate health
and Repair bays don't automatically heal drones.
Hull upgrades don't get applied to drones automatically. And damaged drones don't get restored to 100% health either until they are completely destroyed and/or scuttled and automatically recreated, or micro'ed to manual repair. The repair bays don't recognize them as needing repair and won't automatically heal them. (If you research the tech for 10% more hull, the drones show the potenial for increased hull, but remain at the lower original amount).
Drones are the first thing that most players target. If hostiles remain in the gravity well, they take 6 minutes to return once they are destroyed! And there are so few of them!
I lobby for more and or better drones. Maybe add the option to build constuctor drones in the frigate factory! But at least give them the ability to regenerate health.
P.S. [On a related issue: Advent Communal Labor tech doesn't speed up drone constrution rates at anywhere near the stated rates. And the tier 4 tech to upgrade tactical slots should also grant additional drones.]
