• Doppelganger can now be used even if Force Single Actor is disabled.
• Quicksilver and Doppelganger now uses double-tap feature (Double tap D-Pad Right = Quicksilver & Double tap D-Pad Left = Doppelganger).
• Weapon Switcher's Devil and Sword option removed.
• Devil Trigger abilities and costumes were fixed when Weapon Switcher is enabled.
