Speaking of grinding, I was doing that recently in the new mobile version. (Graphical problems notwithstanding, it's a big improvement over the previous offering. It's still not good by any means, but at least it's tolerable—on mobile. Using it as the basis for the Steam release, however, is unforgivable.)
Anyway, while grinding I noticed something odd: while every other character hits level 99 at 1,743,570 EXP, Magus requires 1,744,830 EXP. Was that difference present in other releases?
