So I took over a project from another dev after he left the company and his project was currently in QA pending release. They were blocking it due to some issues around the persons information not appearing consistently. It turned out he wasn't persisting the persons information in the database with the actual record.

It would be as if when you ordered something on amazon and changed your address for a future shipment all shipments would show the new address. So it turned out QA had no idea how bad the problem was and they had pushed this issue to him to fix but he just wasn't fixing it.

When I reported the problem to my boss and due to the time constraints for release they authorized a contractor to come in to assist. I ended up writing a few classes and one table to persist the data and all of it was solved. I ended up fixing the problem in one weekend. Huge problem and I fixed it in just a few days.
