I was studying my vocabulary schedule 52127 and got to the point where I was almost done up for the day. The end of quiz page after my second to last quiz showed 6 terms remaining to study today. I clicked to start a new quiz, expecting (based on my settings) a 16 question quiz made of the mentioned 6 terms plus 10 unstudied terms, but instead I got a 20 question quiz with only 4 new terms. After finishing that quiz, I went to the schedule summary page and it showed I had no more terms to study for the day. I flushed the page just to be sure, and now it says I have 2 terms to study for the day. I turned new terms off and tried to study the schedule, but I got the popup saying I have no terms left for the day, even though I have listening enabled; turning new terms back on and studying the schedule gives me a 10 question quiz made entirely of new terms, and after it the end of quiz page still shows 2 terms to study. An interesting note: the 2 terms are supposedly level 1, and when I looked at the level 1 terms page, there are a bunch of terms there that are completely unstudied but also marked as known (although I'm pretty sure I didn't do that myself). Yet they aren't appearing when I study the schedule, I just get new terms.
I can almost guarantee it is due to the updates being made to the dictionary. I'll have more information later this weekend as I finish the updates that have to be done by hand.
