I've just noticed that my stats for week 11/16 (2025) are missing. It seems like there's only partial data for "vocabulary", and for "grammar", "kanji" and "sentences" there's no data at all. Is there a chance to regenerate these stats?
Can you please toss me a screenshot so I can see exactly where you are looking?
I may or may not be able to get that fixed. It is certainly possible, but there is no method at the moment to do a single week for a single user (only the full userbase when an error occurs), so I may need to make a decision based on how much time it would take to implement this for what seems to be a one-off issue.
Yes, I've attached a screenshot. I don't find the small drop in the graphs too dramatic, but I didn't want to leave the issue unmentioned in case it affects others as well.
This seems to affect my account as well, so the issue may be more widespread. I checked a few accounts at random from the leaderboard, and they all had zeros or near zeros for that week.
