Unless I missed something, it seems like basically every term I reviewed today gets scheduled for another review tomorrow - even terms with high Mastery. That did not happen before, and I do not recall changing any settings lately - especially "Mastery level spacing" is still set to default values. It's visible as an increase for "Daily study goals" of a given schedule for tomorrow whenever I review a term for that schedule (and answer correctly)
Using Renshuu API I did an export of my schedules to confirm the issue - across all schedules I'm seeing that terms with "last_quizzed": "2026/06/23" are set to "next_quiz": "2026/06/24", sometimes "2026/06/27". Only a few are set correctly into the far future, potentially those I did a few hours ago.
I have a vocabulary schedule 6239664 with basically only higher mastery levels, and still all today's reviews were scheduled up to 4 days into the future
Joining this thread, I think I'm also suffering the same problem.
Doing my morning reviews of vocabulary and sentences, noticed how the stated goals for tomorrow ballooned up and basically reflect the number of terms that I already study plus the intended ones for tomorrow.
I add some example from my vocabulary review that became almost the triple of I usually do.
The same with sentences that became mora than double.
Also have this problem. All of my schedules seem to have anywhere between x2 to x5 the usual amount of terms to review, and a lot of them are already high mastery so shouldn't be there this soon. Woke up, saw how much I had to do today, thought I just hit a wave of old high mastery terms coming back like they do once in a while, then actually started doing them and realized that all of them are exactly the ones I just did yesterday no matter the mastery, and, after going through them all, they've just been added for review tomorrow again.
For me as well, for at least two days (this being the second). Terms I'm sure I reviewed correctly yesterday, with high %, are showing up again today. I have essentially double the number of reviews I should. This includes some terms that reached 100% mastery the day before and show up again. When I answer them correctly, the mastery numbers don't change (nothing turns green) but stay at 100%. I don't think I've had anything three days in a row, but I'm not sure. This seems to be happening for vocab, kanji, grammar, and sentences.
So sorry about that! There was a minor change yesterday that had a bit of a logic error in it. I believe it has been fixed. Essentially, what was happening is that correct answers were moving mastery up, but they were still being scheduled for the next day.
There is unfortunately not a good way to find the damage that has already been done, but it should level off now that the fix is in place.
Yep, can confirm that it's working as it should now, thanks for the quick fix! Maybe it's a sign from the universe that I needed to touch up some of my older terms...
Not sure how internal testing looks, but this would be a really good candidate for some unit tests, since it is core logic. Coding tools could help with most of the work, even if you only give it relevant snippets as context.
