Series are getting uncombined/undeleted

I have recently noticed that series are being undeleted and uncombined. From the Edit History page, it looks like this is an automated process. A few examples:

https://www.librarything.com/nseries/history/19792
https://www.librarything.com/nseries/history/1812
https://www.librarything.com/nseries/history/82888
https://www.librarything.com/nseries/history/14087
https://www.librarything.com/nseries/history/17284

Is is of course easy to redo the deleting/combining, but I guess it is better if a setting is changed. Thanks in advance for looking into this!

Weird. Going down your list, here's what I'm seeing for the last edit:

19792

March 24, 2022

Undeleted the series.
Mar 24, 10:07am

The remaining 4 series

Anywhere from March 24-27

A yellow highlighted message: "Missing nseries_ledger_display_series_unalias"

I'll ask timspalding, smells buggy.

If that first series is going to undeleted, it should at least be a publishers series.

>2 kristilabrie: Could any of this be related to a user who was removed or banned for some reason?

>4 gilroy: Possibly, but I really don't know. That's why I'm asking timspalding.

I'm running through Series edits now. Seems undeleting a series isn't including the member who did the undeleting, at least from what I can tell on https://www.librarything.com/nseries/allhistory

There's also 6 "Missing nseries_ledger_display_series_unalias" messages on that page.

This is still happening. I suspect that it might be related to when the combinations/deletions where originally done. The two examples below were both edited in June 2020.

https://www.librarything.com/nseries/history/50146

Thanks, I've reminded timspalding about this one.

I think this is still happening, see for instance https://www.librarything.com/nseries/history/245 and https://www.librarything.com/nseries/history/4065. Hopefully, there's a fix, thanks in advance for checking!

I noticed that this is still happening, see https://www.librarything.com/nseries/history/14734. For a lot more examples, you can look at the Series Zeitgeist page, under the One-Work Series https://www.librarything.com/zeitgeist/series. Pretty much all of the foreign title series there were previously combined or deleted.

Bumping. I've by chance last month re-combined the one given in >10 SimoneA: so if needing another example of it, see: https://www.librarything.com/nseries/history/18366

Just a notice that this is still happening. A recent example is here https://www.librarything.com/nseries/history/5859. Hope there's a fix for this!

bump.

Silly to bump this without refering to new case. https://www.librarything.com/topic/352320#n8189461

Another bump, as this is still happening, see https://www.librarything.com/nseries/history/277

It seems like some mass uncombining/undeleting event took place, at least when I look at the Zeitgeist for one work series here https://www.librarything.com/zeitgeist/series. All the foreign language series used to be combined, I think. Maybe this is on purpose, as part of testing? Otherwise, it might be a big clue to the cause of the problem...

>16 SimoneA: We're digging into this, by the way. We'll post here with updates.

Okay, we stopped all of the mass uncombining/undeleting Series that were happening, which was being allowed by an undefined user (someone logged out of the site?!). We fixed it so that logged-out users cannot do this, and we'll need to look at seeing if we can reverse the edits made next.

It does feel more like something automatic going on, rather than human effort, that's causing this. See for example:
https://www.librarything.com/nseries/history/60
where uncombinations happened over several sequential days, including yesterday and today. So I am not sure this one has been pinned down quite yet.

Interesting, and there's a lot of the yellow "Missing nseries_ledger_display_series_unalias" lines on https://www.librarything.com/nseries/allhistory that I'm seeing from today, too. Hmmm. Will ask the developers about this.

>20 kristilabrie:

I believe only you can see those.

>21 timspalding: I can see a lot of the yellow "Missing nseries_ledger_display_series_unalias" lines on https://www.librarything.com/nseries/allhistory

>19 Nevov: We are working on this issue.

>22 DuncanHill: Those messages should be fixed now.

>19 Nevov: Re-aliased the series that had been unaliased in the last week or so by the non-logged in user.
