In multiplayer, when a player opens a dyed shulker box (I haven't tested it with undyed shulker box), any players within a small radius, around 30 blocks, have a small chance of crashing.

To Reproduce:
1. Join a server, e.g SMP
2. Go near a player(s)
3. Open a dyed (or undyed) shulker box several times
4. The player(s) will crash at one point when you open a shulker box (though you, the person opening the shulker box) won't crash)
