[MC-74702] Block and sticky piston fuse at world border

I was messing around with minecraft "airplanes" (slime block and piston moving things) and when my ship hit my world barrier the slime block and sticky piston went inside each other. (I was in my private minigame server vanilla) and I DID not photoshop.

Steps to reproduce problem 1. make a flying slime block machine like mine ( this youtube video should tell you) http://www.youtube.com/watch?v=X393TelG0mQ
2. activate the machine and slam it into a world barrier, make sure that the side with only one piston is slamming into the world barrier.
When this effect happens when you try to break the piston it will not break and will stay there, but the slime block will break.
You also can not place blocks on the piston, you can also go through the piston as if it were air.

Either very weird graphical bug or nice photoshop.

Just saying you don't have to do 10 kills in the sidebar objectives for this to reproduce.

(Mini queshton) Ezekiel are you making your own map or something? cuz it looks good so far 😃

Ezekiel 2014-12-02T01:41:57Z

err, I have no clue what the Kills are, they were there when I opened the creative world. If you're asking what's in the background, just my trees from making auto-growing saplings. Not a map.

Actually, the problem is a lot simpler: A piston pushing a block into a block that resides on the world border pushes one block, and turns the other into a "ghost block".

The ghost blocks will disappear upon reloading the game.

This issue is the same as MC-74543, although this issue is more descriptive of the problem.

Seems like it is on every sized world border (not just the biggest)

Yeah, I meant that it does not require a flying machine, only pistons are needed.

If a mod would like to state that "A piston pushing a block into a block that resides on the world border merges them", it would be helpful.

Moving to MC-82010 instead because it has a much more general description.
