The root cause was a previous change in requirements that was not well defined and explored a couple of years ago. None of the original developers are working for the company anymore.
We offered ourselves to fix that bug, but it would take at least a couple of weeks.
This bug prevents us to roll out other deemed important features. But, it is just a bug. No product owner wants it to say to his boss he spent 2w of an engineer solving an issue instead of building another feature.
The boss of the boss called. He says that this bug is not tolerable. He ask us to fix it. We say we agree and we already have screened and have a solution for it, but it will take 2 weeks.
He says he wants that earlier and we say no because no one wants to rush it as we don't want to cause a possible side effect if we fail in something.
The solution according to the is to not fail. Everybody goes back to the planning and no one picks that issue because the condition is to do it in half of time without fail while working on a new feature.
