Since the patch dropped I noticed that my point-of-view in first person has dropped dramatically. Compared to where my eyes would seem to be in third person, I "lose" about a foot or so in height when I switch vies. Put another way, I used to look Lydia in the eye, now I have to look up.
Haven't run into this unless I mine ore while still in sneak mode, then the camera doesn't reset properly. The way to fix it is enter sneak mode and go back out of it. Hope that helps!
Thanks for the tip. In fact, I opened up settings, did absolutely nothing, saved settings, and the problem went away. Odd glitch -- who knows? Might have been a mod behaving badly.
