Description: When falling 10-15 blocks in nether while crouching, fall damage is negated without mcMMO interruptions.
Instructions:
#1. Go to Nether
#2. Exit Nether spawn area
#3. Create a fall area of 10-15 blocks height
#4. Fall while crouching
Recreations: I don't know how many times I recreated it (I was being chased), but I do know that that it only worked for me in that range (the hard way) and also noticed it only works in a full suit of armour.
Result: This bug saved me countless of times until I took a 30 block leap of faith.
Expected Result: There's only one outcome in the glitch, so there can't really be an expected outcome except for the one above.
Evidence: Sadly, I couldn't gather evidence in the panic of being chased by a person, 5 blazes, and a ghast (no drops :()

 

No where did it say *Graceful Roll*, and it couldn't have been feather falling because the only enchanted boots I have are some blast prot. III gold boots @RobertKeller25 gave me.
