Have the same issue with Arkemyr's Robe, though in my journal there are no entries except for this: "I've made it inside Arkemyr's manor. Now I need to locate his vault." I think this is because I did enter his manor once through the bathhouse when I was just new in Neketaka and doing some exploring. I also got the key from Fassina, as well as her tip about using Arkemyrs robes, but the game doesn't register this it seems.
