Autosaves store the wrong image.
The save loads the location mentioned in the description, it's just the image that is the wrong one.
Example:
Autosave 1 description reads "Alvor and Sigrid's House" yet the image is from the tree where the Treasure Map I chest is located.
Autosave 2 description reads "Skyrim" and the image is from Alvor's house (inside)
Autosave 3 description reads "Skyrim" and the image is from Riverwood Trader (inside)
