@bunnypro After trying multiple times, I found out that I have the connection error which is similar to your error for both android and web app on custom sentences only. It seems to be okay with Bunpro default sentences for me. Not sure it would be the same for your case.
@veritas_nz it seems to be a bug with the custom sentences again. I don’t encounter issue when reviewing with bunpro default sentences.
I just tested this and the patch I pushed right around when you posted seems to have fixed the issue. Are you still getting it for custom sentences?
Has anyone encountered this error?
It happened when I was trying to learn new items from the Genki II 2nd edition deck. (Refreshing doesn’t help)
All good now, thanks!
As you can see from the first screenshot, I failed one sentence:
But I didn’t get any new “Ghost Stage 1” sentences:
The same issue seems to happen every few days. I didn’t get any network error popups during the review, and everything else seem to work fine (e.g. slain ghosts disappeared, SRS levels changed properly). I’ll try to get a console/network log next time, but it’s kinda inconvenient because I have to remember it before I start the review, and 90% of the time it works without an issue.
I’m not in any betas, Firefox/Win10 (64bit).
Heya
Just a small bug that happens sometimes on IOS.
It is possible that the “Wrap up pending items” button is clickable when 0 items are pending. When you click the button in that state you get sent to an empty page where you can’t click anything. you have to reload the app after that.
To reproduce:
Screenshot of the button:
Screen after you click the button:
Another for the no ‘Ghost Review’ generation as above.
I just finished reviews where I got 5 wrong but no new ghosts in the ghost list or extra reviews pop up on the schedule in a few hours.
I have (and just checked again) ghosts set to ON, Beta opt-in, dashboard 2.0, using Chrome. Don’t think I’ve ever encountered this problem before though.
Thanks for the great report, the fix will be released with next app update 
Cheers
Hi there! My assumption is this will potentially be caused by a broken Vocab item.
Are you able to show me what word is next in your list to study from this Deck? Please just have a look in the Deck page here and tell me what is the next item in the last that doesn’t have the red Bunpro stamp next to it.
Then I can take a look as to what could be going wrong 
Sorry for the inconvenience and thanks in advance! 
Hey there!
Just checking – you have your Ghost settings to On and not Minimal in the Review settings?
The Summary page is not 100% accurate under a specific circumstance where you don’t properly wrap up your Reviews everytime.
Just confirm to me your Ghost Review setting and I can get someone to look into this for you!
EDIT: Just saw your message @SteveB!
I’ll raise this with one of our Devs
Yes, they are “On”, not “Minimal”, it was the first thing I checked. Thanks!
Hello Thanks for the reply.
I have 7 more from the deck to study according to the summary
The next one on my list is よろしかったら, but I don’t have issues viewing that page
I think the issue might be among the vocab on page 7, however I can’t see it as I receive an internal error when trying to click on it 
That’ll likely be it! Thanks for checking – saves us a lot of time!
Will get one of our devs on the case
Just gonna check with this – the incorrect answer is showing in your Summary, so I’m assuming you’re Wrapping Up your review sessions?
The reason I ask is Ghosts only get created after wrapping up the Review session.
Another thing that might be happening is that you already have a Ghost created for that Grammar Point – so if you have lots of Ghosts this might be worth checking!
At the time of posting I had got 5 incorrect answers in my review set, so it should have made 5 ghosts. 80% of the time I dont click on ‘wrap up’, i just finish the whole set, it repeats any i got wrong during the session, and then presents the summary page where i click on return to dashboard. I have done it this way the whole time up untill now and always had ghosts generated for things I have got wrong
It happened again this evening and likely over the last week or so without me noticing, as now I have zero ghosts on my list (so it cant be the double ghost issue as you suggested) and I know very well I have got a few wrong every session over multiple sessions a day
Edit: On the review screen at the end, it does show that some were marked incorrect on the list, and the little green/red ‘score’ bar shows how many I got wrong in that session
Same as @SteveB , I don’t specifically click on wrap up, but I have the little broom icon on the top right when I get the repeat sentences.
My prev. screenshot contains all my ghosts, as you can see, it doesn’t have one for 「にもとづいて」, the one I failed.
As for today, I kept open my dev tools to get a full console/network log, but as luck would have it, the bug didn’t occur this time. I missed one grammar point, and it properly showed up as “Ghost stage 1”. I unchecked “Disable cache” beforehand to be as close to normal session as possible.
Edit: one thing I just noticed is that for 「にもとづいて」 grammar point, I don’t have a “First Studied” field, see:
Just a wild guess, but could it be related, causing an error during ghost generation?
I have an update on the ghost-not-generating bug.
Today I also encountered the issue. I failed two (non-ghost) sentences, but only got one new ghost. For the one that didn’t properly generate, I’m also missing the “First Studied” field.
I have some screenshots, console export and the complete network log as a .har file. I can send it to you if needed, just tell me how (email, dm). I don’t want to post it here as it contains cookies, session ids etc.
I have an issue where a few items won’t complete. I get an error when I complete them in review, then they go away, but at the home screen they’re still available to review. I believe it’s because I originally tried to forget the items.
I sent in a report for it, but I’m not sure if there’s anything else I should do?
Edit: if anyone else has this issue, reinstalling the app fixed it!
Welcome to the forums, and thanks for the info!
This is for the mobile app then yeah? I’m sure @mrnoone might be interested to know what happened.
