If you fly around in creative mode, your landing may create massive particle effects for little to no fall distance/speed.
What I expected to happen:
Particle blast is bigger the faster you hit the ground.
What actually happens:
Particle blast is bigger based on blocks traveled.
How to recreate:
go in creative, start flying, ascend and descend a few times. Land slowly and from a short distance, notice that the particle blast is a lot bigger than it should be.
