How is this 'working as intended' ?!
It's clearly a bug..
Hmm.. Marcono, when you tried to recreate it did you use /enchant or did you actually enchant it?
I'll try to find out how to recreate it. Give me about an hour.
I doubt that it's intended because in older versions it took damage but absorbed fall damage.
Oh, Sorry. Ill do that in the future.
Nevermind. It's working now.
