There are also a few other minor glitches.
I can't edit Custom flashcards as the save fails. I haven't tried creating a new set but I suspect that that will fail for the same reason.
The system doesn't detect when a new review has been read so the little red symbol showing the number of unread reviews doesn't update.
The display of badge icons next to user names is inconsistent in the forums. Some appear to work and others just get the little blue thumbs up symbol. I also get a the thumbs up symbol when I click on My Account. I also lost my profile picture.
