Oh this is just sick and wrong

But the problem is that you cannot build on a rioting planet. I have this problem too, I sent in a fleet to wipe out the Drushoka, killing about half of their colonies and all their warships in the progress. Eventually, when I checked the scores, they had about .6K to my 1M, so I told them to surrender. They did, but all of their planets are now rioting.
Anyways, they are now in the rear of my empire, and are in no position to be attacked unless the AI starts using warp point tech really intelligently. So I just sent long range colonizers out there to settle a few empty planets and hopefully, once the get there, I can build some temporal vacation facilities. If this don't work, I will have no choice but to displace the entire populations of three systems.
