Windows 7, Java Version 7 Update 21 (Build 1.7.0_21-b11)
When regular torches or redstone torches are placed on cobblestone or mossy cobblestone walls they appear to be floating unless they are at the end of the wall or at a natural corner. I have been able to reproduce the error in creative and I had noticed it in survival at first.
What I expected to happen was...:
cobblestone wall usually looks raised under torches, no matter whether they are at a corner, end or in the middle of the wall.
What actually happened was...:
cobblestone wall only looked raised in end and corner position under torches, the torches along the straight walls appeared to float in the air above it.
Steps to Reproduce:
1. Place several blocks of cobblestone and/or mossy cobblestone wall next to each other
2. Place torches and/or redstone torches on top of the walls at positions other than corners or ends
Or: load map with cobblestone wall with torches at positions other than corners or ends (this is how I first noticed the glitch after 14w08a)
