You can add cyberleg&arm,then add dependent augment, then remove cyberleg&arm but dependent augments will be not removed as was expected.

Let's be a bit more specific here:

• claws augment only works with a cyber main arm,
• mining augment only works with a cyber main arm,
• crafting augment works without any cyber arm,
• jump boost augment only works with at least 1 cyber leg,
• fall damage augment works with a single cyber leg.

Next update will fix:

• crafting to work only with a cyber main arm,
• fall damage to work only with both cyber legs.
