I have a machine empire that just got finished wiping out an opponent. One of the opponent's planets had a few dumpy robots on it that I would like to get rid of as they appear to be much MUCH less efficient than my machine people. Try as I might, I can find no way to displace or even outright kill off these inferior machines. Am I missing something or has Stellaris taken a huge step backwards in how you can manage populations (specifically robots).
