Mine was stuck after Nov, when my citizenship test status was updated. I requested for access to information for my case notes. I received my case notes after a few weeks and I did see that same day they generated the notes, they also updated my other statuses to complete - now only pending oath to get scheduled. My interpretation is that they were sleeping on my application and request for information woke them up.
You can request the notes online from
here.
Hope this helps.
