You know when you try to fix a bug but you end up fixing a different bug you had no idea existed

And after fixing a couple more bugs like that you realise the original bug didn't even exist

Even more fun is when it actually turns out to be two separate bugs that are intersecting with each other in a complicated web of fuckery that leads you down a twisting, meandering rabbit hole of pain, suffering, and suicidal inclinations before you finally solve the riddle. That's always a good one.

@electrineer Or just remains

Nah. I most probably end up with a fix that doesn't solve the original bug and I see a completely irrelevant bug I don't want to fix

Ooh I love those refractors that are basically a bug furnace. Just be careful with crazy side effects that became known as features.
