My race had 2 colonies on Mars. One, I formed myself, and has a population of about 14m; the other was automatically formed by the program, after I defeated some robotic guardians, and they surrendered the increment after that. I never built anything there or moved in any people. It was completely empty.
What happened now.. I had another wave of robotic guardians. I ordered my groundforces on Mars (they were stationed in the prime colony) to attack the unknown race, and this happens:
I had 4 heavy assault brigades, 4 engineer squads and 2 garrison brigades, all with HQ, participating in the battle. According to the above log, only 1 engineer brigade took a (somewhat heavy) hit. There should have been no problem at all.
But.. Now, all my ground units on Mars have completely disappeared. I've switched to the ''all ground units" view, instead of population only, but they're really gone. They're gone from the leaders window as well, for assignments. 10 brigades, and 3 HQ units, gone without a trace.
What's more, the second Mars colony, that was created by the program, has automatically deleted itself.
My Primary Mars colony now lists as 'vanquished'
The freigthers mentioned, that were captured, were mysteriously captured from my, by me. The TG of 5 freighters had split up into 5 seperate TG, and the civilian colony ship was now under my control.
WTH happened? I don't get it.
