Whenever breaking a block, using tools, hands, or other, sometimes a block might teleport a few meters away. The most I've seen is about 10 meters.

The first time I encountered this was when I started a new survival game using the latest Snapshot (14w08a). I began chopping a tree down, and when I finished, I turned around to go to the next, and there was a piece of wood about 3 meters away from the tree I chopped (the tree was five pieces, I only had four in my inventory).

This bug has also happened with coal and iron, so far.

There isn't really a way to trigger this bug, as it seems to be completely random. Thinking it might be due to lag, I tried turning my video settings down, but the same thing happened on very low settings.

Sorry for the lack of picture, but taking a picture of the incident wouldn't really do it a justice. It just looks like a dropped item.

Thank you for reading.
