Fix Version/s: Minecraft 15w33c
Environment:Java 8u25, Windows 10
If you logout with a block in you (works best with enchantment table), you will lower 1 block into the ground!
Doesn't effect non-solid blocks you can walk through, and most solid blocks. Worked for Enchantment Table, End Portal Frame, Beacon, Lit Redstone Ore, Well, pretty much any block solid.
Steps to reproduce:
1. /setblock ~ ~ ~ stone
2. Restart world
3. Fall through block
