Barrier blocks are like bedrock, so no
All I wish is for Mojang is to:
1) Make redstone render when looking at a barrier with redstone on it while looking at the under side
2) Make a bottom texture for repeaters, comparaters, and other items that have no bottom texture
It also happens to the rest of the paintings (2x2, 4x3)
Luckily I noticed that before I went into a world with lots of containers!
Helpful note: Play on a version that you usually play on! It will most likely prevent you from downgrading versions (or just wait until a stable version comes out.)
I wanted to downgrade it so that I can play on the 1.7 servers. I never went on my Singleplayer maps, and when I upgrade versions, I noticed that all my items are there!
