Anyway, I don't think that anyone would actually think that I worked on this for 3 years. But when applied to software (to which this story lead me), I often hear "it took them 3 years to fix this". It's pretty much the same here. The bug was there, it caused serious issues (also with other systems), I applied various random workarounds and I spent a lot of time on it and yet, it got fixed by an accident much much later.
