We know that Skyrim has many bugs that have yet to be fixed. In my current game I have the following bugs and wanted to know if I can fix this.

1. Animation bugs: The patrons of the inn in Riverwoord have decided that sitting in chairs is not enough for them. They now float in the middle in the air, in a sitting animation, 1 meter behind their chairs.
The shopkeepers in Whiterun no longer lean on their market stalls. They now lean on empty air 1 meter behind their stall.

2. Pathfindfinding bugs: Sometimes when I enter Dawnstar or Rorikstead certain NPC's teleport in the middle of the village and then resume their normal activities.

3. I came across a floating mammoth today. It floated in the air and when I approached it fell down to it's death.
