I found a animation bug (game breaking) and a gap in land 'floor' (not affecting game play, but ugly).
Since I don't know where to report them (for Bethesda), I decided to post it here and hope one of the moderators could pass it on to the right people.
I don't know if this has been reported before, but here's a video of what I found.
