The issue I had was that near the end of episode 27, right after Sophia’s scene, the game would automatically skip to the conversation with Nora — without letting me talk to her son and husband first. (The save files related to Sophia and Nora didn’t work, and whenever I tried to load them, a screen with a bunch of code appeared. So I had to start the game from one or two scenes earlier.)
I fixed it by playing without any mods and replacing the old corrupted saves with new ones. Then, once I reached the beginning of episode 28, I saved the game again, installed the mod, and continued playing from there.
If you’ve already tried this and it still doesn’t work, I honestly can’t think of any other solution.
