Hi, I appreciate the quick response.
First of all, I was wrong about when the mod stopped working for me. It wasn't at the beginning of chapter 10, but during or after Lenas shopping in chapter 10. I restarted the game and made the exact same choices until this point, and was able to skip through everything. However, I couldn't skip any text after this point, even though I read well beyond here and had made the exact same choices. The mod seems to be working properly now.
My working theory is that I broke the mod by backscrolling while lena was trying on the fancy dress. During my first playthrough I got a weird graphical error where lena disappeared but the dress was just floating there (of course I couldn't reproduce this glitch lol).
I've attached two saves which should have close to the exact same choices up to the same spot in chapter 10. 9-11 is the mod working and 9-12 is the mod not working. (These are both in easy mode for your reference). I saw other posts with similar chapter 10 problems, but it seems like it's a really specific glitch.
