Sorry for not writing this in a more proper bug report format.
So I was checking out Beta 2-B and I ran into a female adventuer (My Sov. was male) and saw the Ring Icon to get married. So I proposed, and she agreed to become queen. I was able to recruit her from 3-4 tiles away. I then took my Sov in the other direction and sent her back to the city. My Sov continued adventuring, and next thing I know i'm being prompted that my wife has given birth!!! Wait a second...
It is impossible for her to have given birth to the Sov's child, which is why i'm marking this as a bug.
A possible solution might be to require both of them to be together (In a group or city) to have a kid, and make the calculate 2-3 turns before the child is born (so if they are together, than one leaves a kid could still be born for a few turns).
