For the past maybe too weeks I've been encountering a lot of issue while trying to do my flashcards. Very often when I try to do my flashcards I get a popup that says there weren't vectors available to show some of my cards, which is not true. Generally if I refresh the page 5-6 times and click on studies and unstudied terms the issue resolves itself. Today I encountered another issue that prevented me from finishing my review: the last card of the deck is stuck on the review queue.
Have there been any changes to the review logic and is it possible to roll them back? Renshuu has always been fairly buggy but lately the situation has worsened considerably.
