Well I guess you can't handle other people's opinions without saying they have a mental disability. Anyways again, mistakes happen and some stuff just gets messed up. If you are telling me every single clone engineer in the Star Wars Universe never messed up and always did everything right, you may actually have a mental disability. And during the Clone Wars the clones had accelerated aging and spent little time as kids and young adults studying this though they did have effective ways of studying which worked, but trust me that no clone during the clone wars spent 20-30 years on one thing not messing up. They would be old by then as well.
