After getting Hearthfire, I encountered a glitch while exploring a tomb. The screen flashed blue (if I remember right), and I thought the game crashed. But it seemed to recover a few seconds afterward.

After that, I noticed a few things had changed. First, my house in Riverview had decorations and furnishings that I hadn't yet made there. No big deal, there. But I also noticed a glitch in my selection of shouts. There are two titled Drain Vitality, but with different words. The second had the same words as my Mark For Dead shout.

Has anyone else experienced this? It's not game breaking, but it is a little concerning. Was there another shout that should've been in that spot? Am I missing out on one? I don't know.
