I have the opposite problem, none of my own townies or premades are being made into spellcasters. The game just generates new townies over and over to fill those roles. However, they are being used as vendors in Casters Alley, but it's the same Sims the game likes to use everywhere as vendors, not just in the Magic Realm.
I'm wondering if perhaps the reason for this is because I use a custom template save to start all my new gameplay save files. Every Sim in that save is either a copy of a previously played Sim from other save files, townies I kept and liked, such as a couple mail ladies, vampires, etc., and select premades that I've modified to give hot & cold weather clothing only or small tweaks otherwise.
Now, I'm happy the premades aren't being used, but I was rather hoping my own personal Sim townies would have been used to be spellcasters instead of the game generating all these new townies for that role. It's a bit frustrating. Oh well... *shrugs*
