I placed a torch in my mine. All blocks appear completely black. Restarting Minecraft or changing the texture pack does not help.

What I expected to happen was...:
Light from torches.

What actually happened was...:
The world turned into darkness / no lights in the world.

Steps to Reproduce:
1) Dig down a 2x1 hole
2) Place a torch at the wall
3) Everyting is black

Other way:

• Selecting a torch has the same effect.
• Deselect the torch and go to the Resource-Packs-Menu and back to game - everything seems normal.
