When taming a newly egg spawned horse, i opened the UI and threw a saddle on while still riding, which turned my UI's background(behind the UI) upside down till i exited the interface.
What I expected to happen was...:
The background would stay focused on the back of the horses head.
What actually happened was...:
Seemed like my POV was turned on my head while having been looking down at the horse
Steps to Reproduce:
1. use egg to spawn a horse
2. tame it by trying to ride it
3. while still riding the horse look straight down, open inventory and add the saddle - view flips upside down
Happens when the horse is eating, your head mimicks the movement, its a feature! (well not really ;D)
