There is a Mu Ursh colony building on the turn (360) of the save on Balder II in a black hole system. I don't see any other Mu Ursh at black holes. On turn 361, the colony is established and starts with 3 target stability and 0 stability with predicted +1 growth by the next turn. On turn 362, the colony building disappears, target stability is 3.6 and stability is 1 with +1 growth predicted. Seems fine...?
The independent planet Almaak β I has Raaagh, but I can't see if / why it went independent now...
There are 6 planets with Chato but all are owned by the dark red empire, not your empire.
Already indepenent.
Regor α I has Eaxaw and no rebels. Zomg γ I has Eaxaw and is independent. I can't tell why it would have gone independent after it's already happened.
I need a save to demonstrate things going wrong, not a save that has a bunch of stuff that already happened that I can't investigate now...
Edit: Actually, Regor α I does appear to have decreasing stability when an increase is predicted, so perhaps that will work for testing...
