1. Turn on Use GURPS Metric rules in preferences
2. Create Equipment Container with weight 0 kg
3. Create Equipment with weight 1 kg inside container. Total weight equals 2 lb.
4. Change weight of container to 0 lb. Total weight equals 2.205 lb.
This looks especially weird if you turn displayed units to kilograms, so 1 kg item adds 1.1025 kg when I put it in 0 lb container.
This is because Equipment.updateExtendedWeight doesn't check if rule is enabled and relies on WeightValue.add to automatically convert units.
