Cock up
Can't wait for someone to miss something small and make Titan explode.
What do you say after you've blown up a moon ...
'I forgot that Oxygen would re-act with 'Chemical X' and start a chain re-action that resulted in the explosion of Titan', after the moon had exploded, there was a correction in the orbits of all solar system bodies, causing the earth to edge nearer the sun and accelerate the global warming problem. We've got 6 months to live.
