Whoa.
So I left my game on 2x speed for a while, but was too busy to check it for a few days.
I come back, and everyone has passed away from old age except for 6 20 year olds.
Realizing my mistake, I put one of them on "breeding".
So, my game was still on 2x, and I was still very busy.
I just checked it this morning, after like 2 days, and this is what grew from my 6 people village, all from this one guy.
All females above 17 were pregnant and my population was , with probably 3/4 children. oO
