How does one go about getting Lucretia to become a mother?
EDIT-Apparently you need to have a treasure vault built (not one which was destroyed previously) to trigger her mother event. If you build a treasure vault, then enemies destroy it right before Lucretia joins, you might not be focusing on gold farming and miss her as I have. Got to chapter 3 without having her as an available mother, lol.
Anyone who finds themselves in the same situation should build a treasure vault when she appears. The dialogue says something about a treasure vault, but it's not clear and sounded as if she may just want you to earn a certain # of gold, but she actually just wants the building in your labyrinth to exist. It's pretty unusual, I don't think any other followers do this, where they care what your labyrinth looks like.
