I might have an idea of what's going on? Where are MVNTitleMap and MVNSTSOR located in your project? And can you copy/paste your table from step 3 here somewhere I can see it?
Viewing post in Make Visual Novels! RenPy Smart Title Screens comments
They're inside the game folder next to all the other scripts.
title_backgrounds = {
"Title": "gui/Title.png",
"SideA": "gui/SideA.png",
"SideB": "gui/SideB.png",
}
Also I found out that using the jump command anywhere on my script to get the menu to change gives me this error, It's like the label doesn't exist or it's not reading your script :/ (ps: I'm separating the chapters into different scripts, that's why it says chapter1 and not scripts)
While running game code:
File "game/Chapter1.rpy", line 3, in script
jump SideA
renpy.script.LabelNotFound: could not find label 'SideA'.
