When achieving a new level, either by changing it on the Manage Character form, or adding enough experience in the Experience Gains Form, cause the Current Life and Mystic Points to adjust appropriately. If the character is down LP or MP, they should not suddenly go to 100%, but instead simply add their new points so that they are augmented, but with their new level's worth of additional points. Make sure that if the Level is reduced (for some reason) then they lose Current LP and MP appropriately as well.
