Must be a bug. Share me your save file. You can find it in " C:\Users\**username**\AppData\Roaming\RenPy\MUPLUR's-XIX "
Your persistent file was damaged or corrupted. Yet, I looked into save file and everything is good.
The problem is you are in the middle of main mission.
Play the main mission using 'Go!' application and you will be able to talk to Raven after couple of steps
