My "study sentence permanent quest for days in row" went to 0 (without reason ?) and is stucked to 0 since few days (was currently at 193 days in a row T.T).
Could you please solve this issue and have back my previous streak ?
I just checked your stats (or rather, the raw data in the database), and there was one day (3 days ago) that no sentence studying was done. You had 11 sentences correct the day prior, and 14 the day after
While it is possible that there is a bug, this is at the core level of renshuu's logging mechanism, and hasn't had a change to the code in many, *many* years. Again, nothing is impossible, but the chances of that having an issue is extremely low.
I just checked the grammar for your account, and it is also showing no grammar studied on that day - it also shows a higher on average number of grammar terms studied the two days AFTER the missing day, which would make sense if you missed a day and the reviews stacked up a bit.
Is it possible that you perhaps studied close to when your schedules rolled over to the new day, so that it ended up being done the next day by accident?
