I started my first game as a Blood Mage and before completing the first floor switched over to assassin without deleting my first save. When i entered the magic school the first time Azar and some guy with a hood(can't remember his name) aren't there until I talk to the girl standing between the exit to the area and the minotaur. As soon as i talked to her there was a glitch and since Azar seems to think my assassin is a Blood mage. I cant do all her missions(so far the only one I couldn't do was the one on the battlefield) but the school has allowed my character to become a member.
