Block bug

Block turning to 43:8

Before 14w17a, 43:9 (I dont know the New Code) is a smooth sandstone block

in 14w17a, 43:9 has the texture of 43:8, 43:8 is the stone (I also dont know the new code)

Steps to Reproduce
1.Get block 43:9 before 14w17a
2.change to 14w17a
3. 43:8 texture seen instead of 43:9
