A Redstoner called Robobrine sent me his missile factory that contains also pistons.
In 16w40a it crashes, in the previous 1.11 snapshots it doesn't.
If you relog into the world after the crash, you'll continue to crash.
Crash log attached, untouched/not-yet-crashed worldsave also attached.
Steps to reproduce the crash
Simply open up the world in 16w40a and hit the button to the very left, wait for a few seconds.

I can confirm.
Not a dupe. This ticket deals with "Ticking Block entity" while MC-108358 deals with "Ticking entity."
@unknown Yep thanks Neko, I just looked into Panda's bugpost/crashlog and just realized it }=)
Thanks!
@unknown It's actually the same issue. If you trigger with with a piston it says "Ticking Block entity" if you trigger it with an pressure plate (or an entity in any way) it says "Ticking entity".
Ah, thanks!
Can this be reactivated this is an issue again in release 1.11
