Darou?!? Never seen or heard it - my fertility potions failed. Are you sure she hadn't just embraced somebody? They don't have to make it to the hut to have a chance of a child, they only have to complete the embrace.

It could have been she successfully embraced, than drank the potion, and the child only showed up after that animation completed . . . or something. It's only my random guess based on a light-to-medium knowledge of programming, so I may be wrong.
