Yeah I did the same thing, made a new party, started the game, grinded for a long time, got to the bottom of Kawahara and no document. Makes me figure other crucial quest items were lost with the default party I deleted.
I'm not sure if I can reset the scenario? I'm downloading an HDV editor to see if I can put in a fresh scenario disk or extract the character disk and use it in version Relorded version 1 I guess.
