As the title implies, auras that are unequipped when changing builds do not go into the aura inventory.
Specifically noticed with the legacy Invulnerability aura (was in the 4th always-on slot, went into primary inventory bag) and a few of the eye auras.
A specific exception is the HUD aura that is granted from using the Target Locked device 5000 times. This aura did go into the aura bag.
