Applying certain velocities while sneaking freezes Nacho

[Packsolite]

Observed Behavior

Some plugins might occasionally set a players velocity to something like (x, y, NaN) due to invalid mathematic operations or to held a player mid air.
If applying such a velocity vector while the player is sneaking, the server crashes.
