Posted on this but apparently some mod seems to have moved it 'by mistake', but since it is a new bug needing CS attention I'm going to share it again.
Since the patch your Shade will no longer hold aggro but will instead break your stealth and focus all mobs on you.
Unless anyone finds this effect useful I would avoid it until ZOS acknowledge and fix it.
Since this was not announced in patch notes it must be in error and thus needs reporting via this forum, not hidden 'by mistake' elsewhere.
