While playing as Advent, I used the Rapture's Domination ability to capture a Raloz Heavy Constructor. To my surprise, the Raloz Heavy Constructor appeared to retain the ability to build a Starbase. When I tried to use the Raloz's Construct Star Base ability, the 1000 Credits and 100 Metal and 125 Crystal were deducted from my empire's coffers, but the Constructor did not build anything. It would do this every time I used the Construct Star Base ability. While it would be awesome to be able to build TEC Starbases as the Advent, it's probably better to just disable the ability on captured Raloz constructors.
By the way, this problem has an even simpler solution, like the old doctor-patient joke:
Patient: "Doc, it spends resources when I use Construct Star Base."
Doctor: "Then stop using it!"
