Sorry if these have been mentioned before.
After killing the dragon that's attacking the western watchtower by Whiterun near the start of the main quest, its skeleton won't stay in the same place. First it moved to underneath the bridge by the Whiterun stables and now, I've just walked out of Whiterun main gate and its bones are sticking through the gate and half in the ground and it sort of flailed around a bit before sliding slightly down the slope. Not really a problem, but it's a bit stupid.

ALSO!

I saved in my Whiterun house last night and loaded up the save file just now to find all of the walls inside the house have vanished and so have most of the furnishings I bought for it leaving food and bowls and whatever on the floor. Luckily reloading fixes this one.

Just thought I'd mention these.

I've also noticed another small bug. Whenever I pick up iron arrows, the arrow count stays on the screen (bottom right) until I go into the menu.

Edit: Actually, this doesn't happen. It goes after about 30 seconds. My bad.
