Quite little bug report. When I went for the curses at the beginning then did the librarian job for the first time I got -65 intelligence exp. The numbers kept getting further into the negatives.
I will reduce the curse effect in the librarian job a little in a future update, for now I reccomend you to study and level up your intelligence a bit before working if using the cursed mode.
Sorry for the inconvenience (it's not really a balanced mode)
