JaGa is a virtually retired editor who was on Wikipedia just four times in all of 2023, and has not responded to any posts on his talk page since 2016. So that's not a solution; this is not a thing that can wait some indeterminate number of weeks or months because it depends on the eventual return of an editor who's rarely ever around anymore, it's a critically important task that needs to be fixed much, much sooner than that.

I'll note that there is one new page so far that ended up in the incategory search today for the same reasons, but I'm not immediately doing anything about it because of what you said about how the process fix may take time to work through the database -- and also because I've nominated the mainspace move target for AFD as improperly sourced possible self-promotion anyway -- but I also wanted to ask: despite there only being one page currently in the search, the number of pages is being reported as three by the "results" counter in the top right corner. Would this simply be an artifact of the same problem, which will clean itself up as the fix that was already applied here propagates, or would this be a different problem that has to be looked at separately?

This is continuing to happen, with 20 phantom redirects (or, rather, it ''reports'' 20 as the number of pages, but only ''displays'' 17 pages) now in the category and nothing dropping unless I redo the page moves from scratch. This is not a "put up with it" situation; it needs to be resolved.

If it can't be fixed because its maintainer isn't active anymore, then can somebody who knows more about coding than I do help me make a new one to do the same thing? It's a critical tool that can't just be done without, so if the old one's dead and can't be resurrected then a new replacement is needed.

This has been sitting for 21 days without anybody addressing or even responding to it at all. Could somebody advise if there's anything else I need to do to get this at least looked at?

Replag is down to zero at the moment, so I'm going to take the opportunity to add a bit more context. I haven't gotten all the way through the entire batch yet today, but here are all the articles from A through F that should not actually be appearing on the list, as they fall under one of the issues I noted above: Andreas Nödl, Axiom Landbase Pvt. Ltd., BatissForever, Bhaiyato The Hobbit, Bingham Road railway station, Byjus classes, Carrhotus malayanus, Changed people, Changed person, Christ (Lithograph), Château de Bollwiller, Château de Butenheim, Cyclone Victor(1986), Dee Sterling, Diatraea amazonica, Diatraea amnemonella, Diatraea angustella, Diatraea balboana, Diatraea cayennella, Diatraea colombiana, Diatraea entreriana, Diatraea flavipennella, Diatraea guapilella, Diatraea luteella, Diatraea maritima, Diatraea morobe, Diatraea obliqualis, Diatraea pittieri, Diatraea rosa, Diatraea savannarum, Diatraea silvicola, Diatraea umbrialis, Divegrass, Divisor theory, Eddie Mao, Egger Island, Egyptian revolution of 1919, Electrical Trades Union (United Kingdom), Escalo Frio, Faithlessly, Fimbriata.

Just for the record, the current replag isn't the issue at all -- these are all ongoing problems that I've encountered even when replag was at zero. Replica drift may be the issue, or possibly there are corruption issues in en's data in the first place. But my past bug reports over there have never resolved the issues, because nobody ever seems to find the source of the problem -- so it has been suggested a couple of times recently that I try here instead.
