As a builder, I use the block id 100:15, very much. It is a mushroom block with the stem texture on all sides. Since the 1.7.9 update, whenever I place a block of 100:15 it appears with the mushroom inside texture instead of the stem. I tried this with other data values, and they all appear the same.

This is one of the blocks I use most often, so any fix would be greatly appreciated!
