Whenever A Factions Armor is Equipped ( For Example NCR, Legion Or Powder Gangers) Your Karma With Every Faction Is Reset To Default And Is Unable To Be Brought Back To The Way It Was, Unless You Complete A Bunch Of Quests For All Of The Factions. This Bug Is A Common Error And Is Brought Up On Many Forums And Fansites, And A Solution Needs To Be Found For It As It Is Really Annoying Not Being Able To Equip Any Decent Armour..... :cryvaultboy: :brokencomputer:
