Dynasties

Everyone is having their swords disappear, and I have a different problem – if I take off a sword and put on another one, the properties of the first sword still remain, which makes the game very unbalanced and not interesting, and I want to try out all the swords =((
Besides, I've already completed two campaigns with Anastasia and Anton, and I didn't have this problem there; it only started when I began playing as Inferno. I had the properties of 4 swords there -_-
