On minecraft 1.8 snapshots, the redstone is not working correctly, her mechanic got a insane bug. I'm really sad, because I love make redstone machines. I'll let a screenshot. Please, fix the problem the fastest you can. Thank You!

Please DON'T put the description of the bug in the title or summary field!

Duplicate of MC-53384. That's an issue with your resource pack.

@CubeTheThird In Minecraft recent snapshots, redstone dust is rotated if you use any resource pack.
