Again, the title says it all.. Now, I don't necessarily use Frost Walker enchantments, but right when I used them they create actual ice below you instead of frosted ice that "melts" over time behind you as you leave a trail of them. This is actually quite useful for large scale based water tanks, but now it doesn't do that anymore. Please fix this issue at some point...

Oh, and one more thing is that this has probably been a bug even before the Nether Update came. Damn, I'm already starting to feel guilty that I actually needed this enchantment so badly even in Creative mode.
