Well, I've been most fortunate ( or unfortunate ) to receive the Nuoro Mantle from Kane - but there's a most horrible glitch affecting it! It's as if I'm not wearing it, it just floats/hovers in the space occupied by my body.
And what's worse, when I'm mounted it vanishes! With my body, of course, though my head is floating around - instead of being a headless rider, I'm an incorporal rider, lol.
And even weirder this glitch shows on the character load screen. I appear to be dismembered!
