Falling sand entites with a item data of 14 appearing as a purple and black block.

Falling sand appears as a purple and black block.

What I expected to happen was...:
The block would drop as a falling sand block even with a item data of 14. and spawn normally as a stone block. 169 and other light blocks also produce light.

What actually happened was...:
The block spawns as a untextured purple and black block.

Steps to Reproduce:
1. /summon FallingSand ~ ~ ~

{Time:1,TileID:168,Data:14,DropItem:0}
