Oh, weird! Let me see if I can figure this out. Can you tell me two things; 1. In Chapter 1 did you go to the corridor or did you go to the doctor's office? And 2. Did you take the dagger or no?
Hmm... That might have been the problem. If you have any time for it maybe replay a completely new save just to see what happens? I had a few problems with the original game file, so I had to make a completely new one... so if you're using an old save, then that might be what caused the error!! But let me know if it still happens. 🥲
