I played with my friend survival multiplayer at my iPad. Then he was attacked by spider and did not get any damage. Then after 2 seconds he flied backwards 20 blocks and died from fall damage. Accurate version was alpha 0.8.1. Top yellow arrow means the flight distance and two lower arrows mean inventory bug, shows items duplicated, but not actually are.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
Inventory glitch is duplicated by MCPE-6858
