Hello, 2-year anki user here.
Long story short, I tried syncing my ankidroid progress to pc through ankiweb like the usual, and after doing so, the review schedules got slightly damaged (particularly the reviews on the past few days). For the record, it’s totally not my fault for disabling backups (I may have trusted anki’s algorithm a bit too much).
Anyway, as for today, I’m trying to use DB browser to tamper with the database and see if I could just move stuff around to fix it, because the supposed due date from the card info is still intact, but anki reports those cards as backlogs. The backlog date on each card are the same as the last time I answered them.
In the photos above, I screen-capped anki’s report on two samples of card infos for both a normal (due tomorrow) and a broken card (under ‘prop:due=-4’, supposedly only due today), together with the data shown in DB browser where table values about these cards are located.
I have a tiny bit knowledge on executing some SQL commands. My main problem is how do I get the due value for the broken cards using its latest review date’s date and interval.
Apologies for my amazing English usage. I could provide more screenshots as needed. Thank you all in advanced for paying some time to provide possible and or better solutions.
For the devs who might be interested on how I triggered this bug, here are the usual steps I take:
- Sync both PC and mobile through AnkiWeb
- Stop syncing in PC for some days, but keep doing reps in mobile
- Sync the mobile first, then sync the PC
- Rebuild a filtered deck that filters a deck (w/ ‘is:due’)
(This routine has always been successful until today when the decks are showing significantly more due cards than usual so I thought I just forgot to sync the mobile first)
5. So I synced the mobile again.(Or I may have resynced the PC again first)
6. The mobile now shows the same abnormal amount of due cards as the PC.
I use the V2 scheduler with 4 hours daily grace period, and I run a handful of addons.
