All that matters is you don't click on anything on her last instinct vs reason choice, where she's standing in the rain; whatever choices you pick before don't matter. I just retested it, and it should work. Try again and don't click anything during that scene, and if it still happens, If you're able to, can you record that part of the game and upload it for me to see. Cause I don't know how it can go to the bad end if you wait out the timer.
