[MC-70646] Piston Graphical Glitch

I really can't explain it. So just watch the gif

Environment

windows 8.1, java jre8

The gif is too choppy to understand it. Please provide a better video, steps to reproduce the bug, and what your current world coordinates are.

Relates to MC-3718

I go one step further, duplicate of MC-3718

If you want to do redstone stuff, don't do it at the end of the world...

@unknown: If it's a duplicate, then MC-3718 isn't fixed at all (MC-3718 was listed as "fixed" for 14w32a) 🙂
