Hi, thanks a lot for reading and for reporting this! There's quite a bit more content after the first part of the prologue. I'll see what the issue could be and let you know when it's fixed.
Would you be okay telling me which background you chose and whether you see the "End of Prologue Part I" button displayed at the end when completing your background or not, just so I can narrow things down and make it easier to locate the problem? :) If you don't want to say what background you played through when this issue popped up that's totally fine though.
I'm happy you're enjoying it so far despite this!
