You can see whether the database was updated or not by going back to the Review Team Page. It will let you know the status, when it was last updated and give you the current options available for updating the status. This logged-out error won't cause an internal inconsistency in the database, but may have caused it to not have been updated at all.
I will investigate this issue of being logged out. To help with that, when you clicked to update the status had you just logged in? Had you just pulled up the page or is it possible your session had simply timed out? Have you ever had a problem with being unexpectedly logged out on this website before?
