Odd bug here and hopefully make some sense but trying to cast anything from the key ring doesn't seam to work. If I have a hot key like for the mount it works fine but when I was trying to cast my familiars from the key ring it wouldn't work unless I pulled the familiar out of the key ring and put in to inventory then it would apply the stat familiar buff. Also when trying to cast from the key ring it would render my left and right clicks of the mouse unusable. If I merely tabbed out of the game I could get the mouse to work again. I tired this with all key ring tabs and it works the same way.
