Found an issue with Heloise. "Salaza" as I named the daughter, was born twice. It showed the scene two separate times. Once near the start of 4, and once after I had taken Bastion and rescued Cuchilla.
this happened to me to just once in a privet room and once in my room I think the bug might be tied into repeating after big events
Same, she gave birth at arc 2, then she gave birth again after I choose her as a consort
