Collision Handling Override :: Try to adjust Location, But always Spawn
Get Actor Location as the Spawn Transform Location is going to spawn the actor inside the Capsule Component. Actor Location of the character class is Always the center (X,Y,Z) of the capsule component.
Default will spawn it inside the characters pelvis area, then depenetration is going to push the character class out of its collision.
