So, I donāt know if this is connected to your update, but thereās been this weird orange man in the White House for the last few months and he keeps on saying crazy things. There donāt seem to have been so many external effects so far but, yeah, itās pretty weird. Hoping if I just keep hitting refresh heāll go away.
Totally agree with it killing enthusiasm, Iāve literally just gotten to the end of a queue of >2000 items after being off WK for a long time. If these issues last even a few days Iāll just have the same massive backlog again 
My review queue just zeroed out on refresh. Thanks for fixing!
Mine is completely back to 0 again. I only did the reviews once before finding this thread so I didnāt repeat like many others. Theyāve cleared it up now so I have a 0 review queue now. Quiz results are now correctly.
My reviews went up and then right back down and now Iāve leveled up. Also, the timeline is showing no reviews anymore. Issue seems resolved on my end.
This slaughtered my enthusiasm. I woke up this morning and had 130 reviews. I went to work and was slowly doing 10 here, 10 there from my phone while running around. After 4 hours of this I finally got a chance to sit down and do them and the oneās I did just keep coming back. I just did 70 reviewsā¦ Finished and had 45 more reviewsā¦ Finished and had 34 more reviewsā¦ Finished again and had 8, havenāt bothered doing it in last 10 minutes and itās back up to 30 again.
I donāt have time for this shit and itās absolutely painful. I work in software development for a living. God forbid wanikani have actual test environments like any other piece of software rather than put their customers through this shit.
All fixed now. Thank you!
Someone get me a big tranquilizer gun. The Crabigator has lost it.
As someone who also deals with software, I think we both know that sometimes all the testing in the world doesnāt catch everything!
I can echo what others here have said: wait a while, and itāll catch back up. I watched my queue crawl back up to ~180, but now itās back down to 0 again. Iād recommend not doing any more reviews until you see it stabilize. Shouldnāt take too long.
Not even a āsorry we wasted your timeā ?
Seems back to normal. Just wondering, if I happened to repeat reviews for certain items, would the system ignore the duplicates? After a while I got some items right on the second or third try when I originally got them wrongā¦
And now for the questions that I have about this issue (mainly out of curiosity, but also slightly out of annoyance):
-
IIRC, WaniKani was in beta for about a year or more (I know I joined a year before the site went out of beta), and this is the first time this has happened since Iāve been a subscriber. Why wasnāt this type of issue caught in the beta?
-
Does this issue have something to do with the bigger changes that have happened to the site in the recent months? (Probably, but Iād like to know for certain)
If I understand correctly, your session was not lost but will process shortly (if it hasnāt already). I think youāll be fine
Your review sessions arenāt lost. Our background queue was just bogged down. We have upped the resources and any backlogged entries have now been processed.
We do have an extensive testing environment, continuous integration and a pipeline (PR builds ā staging build ā production) before code touches production. Unfortunatelty this issue was due to a lack of resources and not a bug introduction.
This is a pretty major bug, not some minor hidden issue. The entire SRS system was broken. 30 minutes of actual QA would have caught this.
To be fair, Iāve encountered loads of horrendous performance issues following upgrades to Production (including on a team where there were more QAs than Devās for some reason) so I can totally understand that it happens. More annoyed that there was no real response to these threads until they knew how to solve it. Also, why was there nothing on the dashboard like āsoz, Crabigator tired, please waitā and maybe a proper apology would be good tooā¦
I guess this would explain what just happened. Did some reviews, timed out when I got distracted, then started up again and had the exact same reviews in the exact same order come up again.
Iām embarrassed to report that the one item Iād gotten wrong the first timeā¦ I got wrong again 
For what @viet has said already, this was not a bug but more of a performance issue. It was just reviews not getting processed, not that āThe entire SRS system was brokenā
Yeah, or just temporarily shut wanikani down while they work on this rather than letting the issue get out of hand. Put the site into maintenance mode for an hour or 2. Dozens of people were complaining and they just totally ignored it until it was fixed.
