Unfortunately, the only work-around for the Aura of Command bug is to re-load a save where it had not occurred, and hope it doesn't strike again. If you don't have such a game, or do not want to go back that far, you can use
iZakaroN's SaveEditor to remove the skill points you put in Aura of Command. <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" />
