This afternoon between approximately 1:30 and 3:30 (east coast time), I was doing the quest: Mists of Corruption, which eventually leads to killing Angof. I was on that part of the quest where I had to follow Mage Gabrielle into a crypt.
As soon as I stepped across the threshold and into the crypt, I noticed that there was no floor. The entire bottom/floor of the crypt was white, and my character spent about 3-4 seconds falling to her death. She recovered at a nearby wayshrine.
This may not be useful, but I thought I'd pass it on anyway: On two different occasions in the last week, I was riding on my horse outside Daggerfall, when I clicked on the screen to make my character reverse course (do a 180). For a split second the screen showing my character and the outside world was replaced by the opening screen when you first load the game. It was for a very short time, no more than 1-2 seconds, probably closer to 1 second.
