Double hopper clock broke

Please describe the issue in detail. Please provide exact steps to reproduce the issue.

I made a sugar can farm from ImpulseSV called: Minecraft Tutorial: Cheap and Easy Lossless Sugarcane Farm
This one https://youtu.be/Lxg6H9rFfJQ

I copied the farm to the other side of the pistons and red stone block so I could double it.
In 1.10 it works super. But in 16w39c it broke and doubled the slime blocks or the slime blocks got stuck and wouldn't retract anymore.

Tried it on snapshot 16w40a and the game kicked me out when I was standing next to the hopper

and the game kicked me out when I was standing next to the hopper

"kicked me out" means ?

Please attach the game output log of the Launcher after that has happened again.

This is my first bug I report so I hope I am doing it ok 🙂
Btw I am in a building with a pumpkin/melon farm and a cactus farm.
The cactus farm is without red stone and the melon/pumpkin is with red stone.

kicked me out means: stops the game and only the launcher is active.

Here is the log:
