Affects Version/s: 220.127.116.11
Fix Version/s: None
I have confirmed this glitch by experiencing it twice.
I was building a staircase in the Nether, and took some minor damage from a Blaze fireball.
I died instantly.
I've had this happen to me twice. I had full Protection 4 diamond armor with a Notch Apple's regeneration going.
So, in short, standing on staircase, hit by blaze fireball, dead at 100% health instantly.
PLEASE FIX SOON!
