After the fight with Damian/Nora and after Nora went inside I encountered a bug. A "Lass" Character had blocked the entrance after Nora went inside and is now preventing damian from getting through, thus making it so I can not continue my game at all. I hope you can fix this, I am no longer able to progress the amazing game. This is a major concern!!!
---Since bug happened I recovered an old version of my save, still needs to be fixed---
