While playing survival on normal difficulty, I stumpled upon a bug where even tho my hunger was full I still didnt heal.

What I expected to happen was...:
My life would heal back up when i have full hunger

What actually happened was...:
Even tho my hunger was full I didnt heal back up, when i got down to about 3 hearts I began healing again, But I don't know if that was because i had deleted some files, clearing up some space on my local harddisk.

Steps to Reproduce:

I dont really know how this bug happened, but i will write down what i was doing before i noticed the bug

1. Fall and take some falling damage while having 8 or less hunger
2. Walk around, Dig some dirt and stone, ect. to make your hunger go down until you have no hunger left and begin to take damage
3. Fill up your hunger using Sweet Berries
