I wonder if it's ghast proof? I also wish that there was a nether-creeper, like a normal creeper, but it's red and in addition to exploding, it would also catch stuff on fire. (P.S. Sorry if I sound nooby, becuase I kind of am, I got this game about a week before the 1.8 update.)
If I see it right, there is a block burning on the bridge ( bit to the left of the center). Does this tell us, Netherbrick can burn indefinitely, too ?
Unfortunately it seems that Mojang won't even acknowledge the low FPS problem (4-7 FPS on 1.8), so I guess I just don't really care anymore.
A new block or distorted coloration of the picture.
but i dont think, that this is nether brick...
for me it look more like a sort of nether wood planks.
