Oh, sorry, isaiah58. I misunderstood. Mea Culpa! Still, it was unusual for my assigned shop to disappear from my list without any issue. It was in my assigned log, and they did offer a bonus. And when accepted, they confirmed but it disappeared for no reason. They had no explanation for it. But then again, MFI had been having website problem.
Completed shops disappearing from log simply must be dealth with asap. I would contact Help Desk right away. This is a major issue.
