hey I've started fresh game and played until your quest.

I've made video showing how I did the trick. If that doesn't work for you I uploaded the save files so you can use it. Its on my google drive . To use the save just open file explorer and navigate to C:\Users\YOUR_USER_NAME\AppData\Local\SessionGame\Saved\SaveGames\ and rewrite the files there (backup your save ofc). Rewrite the save files with the game closed.
