So I was opening one of my world and collecting my Nether Brick from the oven.
When i went to the Crafting table it didn't show the Netherbricks Block item...which was weird. 
My mind went like Oh and then went over to my chest where suddenly all Nether Bricks blocks stack were now Stacks of Nether Brick..... I believe this is a bug that I can report since I wanted to build with the brick...but it's not there. restarting pc didn't solve the problem.
I left two screenshots for you guys.

...wait...I just lost my stacks of Netherbricks....godver xD
