FVector_NetQuantize10 LastPreAdditiveVelocity
Saved off pre-additive-applied Velocity, used for being able to reliably add/remove additive velocity from currently computed Velocity (otherwise we would be removing additive velocity that no longer exists, like if you run into a wall and your Velocity becomes 0 - subtracting the velocity that we added heading into the wall last tick would make you go backwards. With this method we override that resulting Velocity due to obstructions
