That was a great game back in the day, it was one of the few games they stocked at my local rental shop and I probably rented it 100 times before finally beating it. I might have to revisit that game at some point, maybe even go for a few of the achievements.
I did not know this, it all makes sense now.
I say "glitch" but many people think it was done on purpose to make the game longer. Who knows. Stat growth is worse, enemies are stronger and you learn skill slower so the game is infuriating if you try to start as a spell caster. You can probably find more details by googling the game, it's fairly well known that the English version is much more difficult because of this.
