Problem: Some skills assigned to a character are unusable in battle, while others work. There is no error, they are simply grayed out.
Information: The skills are assigned to a custom skill subset. Each one is assigned to the correct type. Animations are assigned. The character has enough MP to cast the skills. However, the skills are gotten through a class change that happens in game. I do not see a reason for the skills to be unusable, which has left me perplexed.
Help would be appreciated. If you need to know more, just ask.
