In the inventory you can use the mouse wheel over the character to zoom in/out, by default this view is very zoomed in which I find annoying so I like to zoom it out, but this bug will reset it.

When the player has their inventory open, and then it gets automatically closed due to the falling animation, the position will be reset.

1. Climb on an object
2. Open the inventory and use the scroll wheel on the character to zoom out
3. Walk off the object with the inventory still open
4. As you begin falling, the game will close your inventory automatically
5. Open the inventory again and see character zoom level reset to default

If you fall from an object without the inventory being open, then the bug doesn't occur, which you can see once in the video.
