I'm playing on PS4, and in chapter 9 after all the trail of light stuff, when you go into the basement to find Dr. Colden, i pick a direction and start walking down the corridor until Pierce says "What's going on? It never ends" and then i can continue walking and nothing else happens. I've tried just walking in the same direction for 5-10 minutes and nothing, I've even tried switching directions and nothing happens. But with only one save game i have nothing to reload from earlier in the game. Am i missing something?
