I am not gonna log this as a bug as I personally do not believe it to be.
I have noticed that even if there is a rework station (and in my case 3), that a defect is sometimes generated by the rework station.
I think is is quite realistic, but am posting about it as I would like to get clarity on whether or not it is a bug.
To clarify, the vehicle had a defect in station 1 that was fixed. Moved through QA on station 2 with no problem and the developed a bug coming out of station 3.
Awesome update Cliffski.
