hurricane boots are pretty much broken for me, when I press 'g' to turn them on, the message displays saying that their on but the sprint doesn't work and once they have been turned on, flying is unable to be turned off. But these bugs are only limited to smp. I also take fall damage in the nether with full redmatter armour and a gale/ ring of arcana, which makes doing anything close to flying impossibly dangerous, I've been turning fly off and landing in lava to break my fall but that has its own dangers... if there isn't enough lava to break the accumulating fall damage all my stuff is gone :|
