I just loaded a new survival world on snapchat 16w02a. I started to punch some wood from a tree and when it broke it reappeared and then broke again a few seconds later.

What I expected to happen was for the wood to break and the item to go into my inventory instantly.

What actually happened was that when I broke the wood it broke and then reappeared and then broke again for good a few seconds later.

1. Go into a new survival word on the snapchat 16w02a.
2. Find a block and start punching it until it breaks and the bug should occur.

Thanks
