So I have 5 women who are all caring for babies, and have been for over week (my time). Their counters all say they've been nursing for 120 minutes, and have for quite some time. This is ALL of my fertile women. They never seem to be finished! And the other villagers have stopped aging. I've been running the game at 2x speed and left it on most of the day, yet nobody's getting any older! What's the deal?

eta: just checked again, and they all say they've been nursing for 400 minutes...
