I wish someone had told me how common this was back when I worked myself to death fixing every UI abnormality that no one except some misincentivized testers used to report at my first job. At the time I thought it was dishonest to say something was irreproducible and it'd be beneath me to patch an issue knowing it'll sprout ten others.

I'm proud of fixing everything properly but I won't repeat it ever unless the company actually has that high a bar across the board.
