The plugin's crash-safe collider setup was issuing physics resets during scene load. Each one restarts every atom's settling, so scene loads could last for minutes. The hand now waits until the scene has fully loaded, and only after scene load it spawns and builds its colliders.
New: 'handAllowed' toggle: a second on/off switch next to handEnabled. This was added so my timeline animations could trigger handEnabled, while also having toggles in the scene to manually enable/disable a hand.
