Are you referring to the Revan's chestpiece vs the classic Revan's chestpiece?
I know that those two are different and the classic has the hood down. I kind of thought they had the them both available to give us the option of hood up or down. I don't really see how there could be a problem with that. If its some other issue that I'm just not seeing, then pay no attention to me and I hope it gets fixed.
It's a BUG.
Basically when he has his hood up he has a 2nd hood down. AND when you get rid of the hood up by wearing a hood-removing headpiece, half of the 1st hood remains giving you 1.5 hoods.
I repeat even when he has hood down, he still has 1.5 hoods
