I think since they updated my status with the RFE information, the FP update got superseded by the RFE update. So they may have my FP, and now want additional information.
Another take on the situation is that I called the BCIS on wednesday to complain over the delay, and the person told me that she'd put in a request to see where my case was, and that I would get a reply within 4 weeks. And on Friday they issued the RFE. Now I am not a suspicious person, but a few does ago a thread was posted here that made the assertion that if you call an IIO and complain, they issue RFE's ...I think that may have happened in my case:
