Could you try to set up a save a turn before such a terraforming event occurs then? Maybe it will lead to reproducible famine several turns after the terraforming happens?
The save files turn 288-291 that I uploaded should be useful (under Save.7z). Turn 288 has the sitrep message "Gaia transformation has been produced on Sirius I"; the turns after that have the famine sitrep message for Sirius I (did absolutely nothing those turns). I checked twice - the famine sitrep messages appear after the gaia transformation takes effect (so from turn 290 onwards), so that's why I think it has to do with population growth.
So the save doesn't produce famine for you? Is there any point in my downloading it?
It did when I was playing, but when I reloaded it and tried to reproduce it, it didn't
. So probably not, but it's in the same folder with the other saves I mentioned above. Just delete it or something I guess.
(Update to the latest testing release)
Downloaded it. I'll test using this build from now.
