When you complete the Shadow portion of the Solar Arc, Bolthy Patterndancer appears as a trainer like it should. If you talk to her, she offers you all 3 spells for 1 training point each instead of giving 1 for free. I thought this was a change and bought my spells with a training point. After speaking to the Emperor he sends you back to her and she gives you one for free. So I lost a training point on my Myth wizard because I bought 2 spells, one of which was rewarded me again for free afterwards.
