Dynasties

Everyone has swords disappearing, but I have a different problem: if I take off a sword and put on another one, the properties of the first one still remain; it's very cheesy and makes the game less interesting. And I want to try out all the swords =((
Moreover, this didn't happen when I played through two campaigns with Anastasia and Anton; it only started happening when I began playing as Inferno. There, I had the properties of 4 swords active -_-
