This hood is something I was looking very forward to wear, the fact that it's glitched is extremely frustrating. Is Bethesda even aware of this? And when will they take care of it? Honestly this is a fairly small ''glitch''. I suppose they could hotfix it, could they not?
And no, I can't just stop being a vampire(I am well aware of the fact that vampirism causes this bug/glitch). I wouldn't even attempt to wear the hood in the first place if I wasn't a vampire. The reason for that is that the Hood fits vampires perfect.
Also, it's not only the Guild Master Hood. Linwe's Hood seems to be bugged as well.
