Currently I am playing through KOTOR 2 a second time as a light side Jedi, and I noticed that the bonus reduction in cost adjustments for my lightside force powers have reduced, and my universal powers have actually gained cost. On my darkside game, when I reached Dark mastery, my costs were cut in half for DS powers. Is my copy of the game going crazy? I suspect that it may have something to do with my prestige class, but it doesn't state that anywhere in the prestige descriptions. If it helps, I'm a level 16 Jedi Consular/ level 4 Weapon Master with Light Side Mastery. Thanks.
