Not sure if you're aware of it already but I found a bug with Valeria fights where she takes on the height drain characteristics of the last person I fought. Once I drained a ton from her with dom/sub and belial curse but then came back to find Sehkmet at severe negative height and Valeria at just her height minus my win bonus. As a side note I'm having trouble figuring out how to win and also Izel is just unkillable because she disappears after my first fight with her of the day and goes on a rampage faster than I can reduce her height.
edit: I should probably clarify that I'm on version 7.9 win
