Okay, so I have no idea how this happened (but it occurred at some point while I was in the Saarthal excavation site finishing the Forbidden Legend quest.) I noticed a little bit afterwards that I was pretty much invincible. My health says "5368/56" (whaaaa?) and even when I completely take off all armor and have a bunch of enemies unleashing hell around me, my HP doesn't get touched.

Now, this might be fun for some players, but I like the challenge... Has anyone else come across this glitch (or if it isn't one and I'm completely [censored], is there a reason why I have infinite health?)
