Bug: Pack and Unpack nodes explode Vectors 4, 3, 2

The incompletely connected «Pack Vector» and «Unpack Vector» nodes do strange things

See: Vector3 bug (Similar test with Vector2 is the worst)

Hmm I don’t understand why you don’t have default values editing fields on Pack Vector3 node X and Z inputs. It looks like this for me:

There are 2 types. Each for its own case (located in different places: Packing & Vector3, for example)
typesPackUnpack

This
PackVec3

Bonus:
To make it clear what was meant

(If in programming velocity.y + = gravity * etc.
Then trying on local visual nodes, the result is something like this)
