We have had similar experience after our last FP in May.
It seems that status reverts to an older status the day after the FP are taken
and updated in the system.
Did you receive an RFE earlier? If so, then yesterday's update might be
a reverting to that old status.
If not, then it would make sense to keep checking with your lawyer.
Also may be u can just call TSC IO via POJ and get it confirmed.
