Lost Homeworld, no Civilians?

[Malorn (OP)]

Due to his new campaign, It seems that Steve will have to solve this bug soon...

At least in 1.12

True enough, but my guess is that I could have switched things over if I had done it BEFORE I lost the homeworld. At least, that's my random guess at it. Haven't tried that yet, but it would explain how it snuck in.

Bit of an odd situation here. Because of how I set up my game, with many NPRs on earth, and myself with only a small presence there, I ended up losing control of earth entirely. This was fine, I saw it coming and had already moved everything offworld while my poor troops fought a rearguard action.

All well and good, at that point. But then I found something a bit odd. Suddenly my civilians stopping spawning...entirely. I effectively had no 'capital' to connect things to, and soon retreated completely outside of the Sol system. It's been 70 years since then...still no civilians. Am I missing an obvious button to create a new capital?

I have a planet with more then 3 billion population on it currently, and several other planets with over 300 million. Is this just something no one planned for?

I forgot the 'New Capital' button. I'll add for v1.12.
