Which build of the game are you playing? If it's a number lower than 1.6.1, this is an old bug and should be fixed. If it's 1.6.1 or 2.0, then I need to go bugfixing again.
I checked and it says 1.6.1! I'm also not able to access Chapter 2, either when loading my previous save file from Keir's route, or when I replay the game from the start. Thank you!!!
