First of all, thanks for alerting me to the slate bug. I, too, finished Todelmer quite accidentally, and I've restored a previous game so I can finish it for real.
Secondly, this has probably already been discussed somewhere since it's an obviously very irritating shortcoming of the game, but I can't find a discussion for it anywhere else. Is there some kind of fix to allow me to skip to the last page of the journal or the dialog book? It's really annoying to have to flip every page every time I want to record more thoughts in my journal.
