I destroyed a large fleet of Precursors and conquered the planet that they were guarding. My Xeno team found 1,747 xeno-archeological sites on the planet. Started exploiting them, and of course hordes of Giant Killer Robots came swarming out.
I had started a colony on the planet. When the robots attacked, the colony surrendered, even though my combat odds were 99.7 in my favor, since I had a large stack of ground units there. Bug?
I've removed all the colonists to a neighbouring world... will this prevent the "surrender" bug from recurring, or do I have to disband the colony?
Is thre any way to speed up the process of recovering the goodies? Will a big stack of Engineers speed it up? At a rate of five or six discoveries per year, it's going to take centuries to clear this site.
