Im finding alot of Mammoth, Daugr, Goat, and just about anything you can think of falling from the sky... I 'think' its immediately upon loading following a fast travel..They appear about 100feet in the air, then fall to their deaths.. While i understood the placement of mammoths, elk, deer, goats, etc. The 2 Draugr were next to My Hearthfire created house from Dawnstar! Never seen Draugr wanderng the hills/forests/grasslands...
