I'm curious as to how that happened. Were you playing in Hard Mode, because I find it's dangerous to leave the game on 2x for too long unattended in that mode. Did you leave more than one farmer selected, and were any doctors selected (preferably two in case one doctor gets sick and needs healing)?

I'm not positive what went wrong, but i have a sneaking suspicion that my women were dragging every available man to the hut. I had put them all on breeding for a period of time. Before i went to bed, i switched them to their more respectable proffessions, but i think they preferred the conjugal hut to research.

So we don't get tech points for learning to farm, build, heal or breed? Only for research?

only for research

I finished my first village. All 16 puzzles, a population of 90 and only 9 deaths.
