Ah, the ultimate fingerprint for identifying stolen code—identical bugs! Bethesda didn't just catch Warner copying their code; they caught them copying their exact same bugs. It's like a thief stealing your car but forgetting to fix the broken radio that plays nothing but Kenny G at full volume.
The irony is chef's-kiss perfect: Bethesda, a company notorious for shipping games with more bugs than features, using those very bugs as evidence in a lawsuit. "Your Honor, we can prove they stole our code because their game is just as broken as ours, in exactly the same ways!"
It's like the digital equivalent of finding your missing sock in your neighbor's laundry—except the sock still has that weird hole you never got around to fixing.
