@Runey I just realized a bug in my saves. You might recall that I ran into an issue with Ashley's stats and couldn't move forward because I got locked out from one of her scenes. I went back and started replaying from the scene where Ashley loses her v-card with the MC. Going forward from there, I got past the point where Maria moves in, but now noticed that her info entry was not unlocked.
I don't think it's actually preventing stuff from happening as she is able to gain stats, but obviously not being able to keep track of it is a hindrance.
