[ARCHIVED] [ROM] Sages wont teach spells even though friends

I had this today with Simeon, which was weird since his friendship bar is max green with my spellcaster. Then I started thinking and checked, and my spellcaster has learned all the spells that she can learn at her caster level. When she asks Simeon to teach her a new potion, he says she's learned all she can. 

In my case it's clearly just a lack of appropriate refusal text, the sage uses the 'don't know you well enough', instead of explaining that you need to get to the next level before you can learn new spells. Not sure if this is the case with the others, but worth checking.
