This is ridiculous for so many reasons. Comparing a minor bug with player speed calculations in an edge case scenario with the total collapse of a bridge. They are on totally different scales. One cost lives. The other is a minor inconvenience at worst. When bugs are found you triage them, and if the expected cost to fix is greater than the expected benefit gained, you don't fix it. The benefit gained from fixing an edge case movement bug like this is minimal, so it will often be left unfixed. This isn't incompetence, it's just prioritisation.
