There seems to be a problem with the armor attribute. It seems like it is not stacking all of the armor on top of each other. It takes the value of the armor in the first available armor slot(By that I mean the first one that has armor in it.) and then uses that as the overall armor rating when worn.
Head Value = 1###########With Bug:
Chest Value = 5 ##########Total Value = 1
Legging Value = 3 ########What Should Happen:
Boots Value = 1 ##########Total Value = 10
The pictures bellow demonstrate what is happening with the armor value. I have never had this problem before so I don't know what to do
