First off, I'd like to say I'm playing on the Xbox One and I'm not sure how much of a difference there is between PC and console, so just a heads up

.
So I play a Bosmer NB with medium armor and a bow. My character is pure stamina and I'm all about stealth and crits. I've pumped a ton of skill points into my character to make him have reduced cost for abilities, high stamina regen, etc and I've always been proud of my insanely high crit %. The last time I checked I was around 54% crit, but recently I see that it has changed to 37.5%. While this is still a decent number, I'm frustrated because it's supposed to be a lot higher than that. Nothing has changed ability or armor wise, so I don't understand why I'm missing 20-ish % on my crit chance. Did something get changed/nerfed in the newest update? I do notice that when I use Shadowy Disguise that I get an extra 100% tacked onto my current crit %, but other than that it stays the same. Thanks for any replies, I really appreciate any input on this.
