After invading one of the Tantik's planets, I was asked if I want to liberate the Gargals living there. I chose "Yes" (Option 1, I think) and expected the Gargals to be reinstalled as interactable race but this did not happen.
So I think there is a bug either on one or the other side.
Scenario 1:
The idea was that a once wiped out empire shall not be installed ever again as it has no government. If this is the case, I don't see how above mentioned question makes sense. I'd rather expect that I have the same choice as if I invaded the planet first (assimilate, exterminate, enslave) but with assimilation going to 100% more quickly. Something like "The Gargals are happy you have evicted their occupying powers and ask to join you."
Scenario 2:
The question is there on purpose. Then I'd expect the race to be reinstalled with good relations to the liberator.
Scenario 3:
The current behaviour is intended exacly like it is. If this is the case, please explain the backing thoughts as they evade me
