I try to fast travel from Whiterun to Anga's Mill, and the game has me arrive quite high above the ground. So then I fall and die. How do I make it stop doing this?

Edit: Oh just so its clear, i've done nothing different than the other 10,000 times ive fast travelled without incident.

Do you have any mods?

The Mill may not be rendering correctly. If a reboot of the system and a reload of the game does not sort it, then FT near the Mill and then walk up.
