When i enter command "/effect @p minecraft:levitation 30 254 true" with gamemode 0 or 2 and fall a few block below with low speed after taking more than 0.5 heart damage from falling i'm bouncing about 50 block up (even when i'm falling from 5 blocks)
I expected that i just land on the ground
bounce at the height of 17m
1. build at least 4-blocks high pillar.
2. stand on top
3. type that command: /gamemode 0 (if in creative)
4. type next command: /effect @p minecraft:levitation 30 254
5. fall from pillar.
6. when you touch the ground you will be launched 17 block up.
Confirmed on 15w31b, you launch back up if you hit the ground while levitating.
And it keeps happening.
*NOTE : it only works when you fall from a 4 block high pillar (and higher).
