- Affected Service (Just build): -
What was affected - Europe reigon, just build arena.
-What is the bug?-
I discoved a bug that allows the player to leave the just build
arena just in vanilla minecraft. I accidentally discovered this when
playing on the hive and I thought I broke my favourite server. 
This bug allows you to break blocks outside the just build arena (Walls and
floor) You have a system to stop this, but I found a problems with it.
Basically, if you are 5 blocks away from the block you wish to break, you
can fly quickly and hold down the break button (I use pocket edition so it
is easy to do this by accident.). Then in about a 30 percent chance the
block would be broken showing the outside. You can’t leave though that is
great 
. But in judging, it doesn’t have the same system. A player can fly
out of the arena.
Please fix this, I am slightly concerned what will happen when other people
find out. Possibly try using clone commands or adventure mode to stop this.
