Honestly, I’m not great with this stuff either, so I thought you might have the same issue I did. That’s why I tried this fix, but maybe I did something different for it to work. Still, here’s what I’d suggest you try again:
- Close the app completely.
- Go to your game folder, then to the "script" file (it might show as scrip.rpy for you).
- Search for “show screen sophia_atschool”.
- Right above that, you should see a line that says “if sophiaphase2interaction1 != 0:”.
- Change the “0” to “1”.
- Save the changes and load your save game.
- Make sure it’s morning in the game and head to the classroom where Mia is.
- Check if Sophia appears there.
If it doesn’t work, try deleting the game and redownloading it. Then repeat these steps from the beginning.
