A recent twist on this that I have noticed is that once you find and fix the bugs and check them into source control, get them tested, approved, and pushed to live – someone will then revert them for reasons that aren’t clear to you, which then starts the process over again.
So not only do you have the annoying bug, you have a billion emails going about discussing protocol of who is most wrong, whether the bugfix is valid, and who does what fixes.
I always am amazed by how every time I think something like that is incredibly annoying – it always gets worse.
At the moment, the people working on my codebase are me, me, and me, so I only have the problem you describe when I’m having a really bad day.
My wife is asking me why I’m laughing so hard.
Limbo is filled with bugs that don’t manifest until you notice it in the code while looking for something else, but then it starts happening for everyone once you see it exists.
