Normal for me (Valan was in the Academic List)
Did you restarted the game and try again? Or did you didn't have Valan?
Of course it WAS, that is why I stated it Disappeared. It would be more informative if someone can say whether it IS in thr Heroic Academy list as obviously it is not in mine.
Also, what dumb question is this? Of course I must be having it for it to have appeared then disappeared!
